Boiler cashback for small and medium sized businesses in London

Heard of the Cleaner Heat Cashback scheme? If you’re a small to medium sized business (SME) based in London, this is something for you! The Mayor of London is funding an offering that will enable SMEs to claim 30 to 40 percent cashback when replacing an older, inefficient heating system with a new, cleaner one. The scheme is part of Sadiq Khan’s £10 million initiative to improve the capital’s air quality.

In terms of benefits; other than a new heating system (that’ll cost you less) and a saving of up to 25 per cent on energy bills, you’ll be doing your bit to help improve London’s air quality and also contributing towards meeting the Mayor’s ambition of a zero carbon city by 2050, through a smaller carbon footprint.

Some interesting environmental facts (just to spur you on) in relation the pollution happening in London:

  • 7 per cent of London’s NOx (Nitrous Oxide) emissions are the result of commercial gas consumption.
  • 40 per cent of carbon emissions in London come from non-domestic buildings.
  • 187 air quality focus areas across London show high levels of air pollution.

As well as reduce harmful gas emissions, the Mayor’s scheme aims to boost commercial energy efficiency across the capital.

The Mayor recognises London’s air quality as a public health crisis. It is estimated that thousands of Lndoners are dying every year from long-term exposure to pollution. In 2010, London air pollution was linked to 3,000 hospital admissions and the economic cost of these health impacts is estimated as being up to £3.7 billion per year.

To find out if your SME is eligible for the cashback scheme, CLICK HERE and do note that the initiative operates on a first come, first-served basis. To apply, you will need to provide:

  • Your business details

Boiler replacement – global internet retailer

The life expectancy of a boiler depends very much upon the type of boiler in question but, on average, a traditional gas boiler should last between 10 and 15 years. When it comes to the end if its serviceable life, it’ll need to be replaced – as was the case when we were called to check out some issues a client (global internet retailer) was having with their current heating system at a warehouse in Croydon.

The team at CH Systems discovered that the older gas fired Reznor units had fulfilled their life expectancy and a decision was made to replace the current units with 6no new Reznor UDSA-100 units.

With the roof of the warehouse being 13 meters off the slab, the work had to be carried out on Mobile Elevating Work Platforms (MEWPs) – this was no problem as all of our engineers hold current IPAF Certified Training For Working Height certificates, which enabled us to carry out the work in a much more timely fashion (saving the time and effort of scaffold towers etc). See pics below:

Boiler service and burner replacement – Shoreham Power Station

An existing client that has a maintenance contract in place with us for their boiler room at Shoreham Power Station requested a major service on their 4no Potterton Derwent Prestige boilers.

After completing a thorough clean of the burner, flue ways and heat exchanger we commissioned the boilers back into service but we were unable to get a satisfactory Flue Gas Analysis reading. The Prestige boilers are fantastic units but at 19 years old, time is taking its toll; the decision was thus made to replace all of the burners.

We are pleased to report that following the installation of the new burners and the re-commission of the boilers into use, we achieved the best readings we have ever seen on these units! See below for an idea of what the burners looked like pre-replacement:

Gas line installation – global online retailer

Christmas is around the corner and as one might imagine, retailers are operating in sales overdrive; so when we were commissioned to install a gas line to an existing Lennox Air Handling Unit (AHU) for a global online retailer, the team at CH Systems was prepared to work ‘out of hours’ so as not to disrupt operations (never a problem for us!).

The work comprised the installation of 80 meters of 76mm Geberit Stainless Gas pipework and fittings, which took place at an ‘above level’ working height  that required the operation of scissor lifts to give us access to the gas line. We opted to use the Novopress ACO203XL pressing tool as this meant we did not have any trailing power leads (created by the height at which we were working) and this managed to avoid any potential Health & Safety safety issues.

See below for images of the installation in process:

Freezing and enabling work – Royal Chelsea Hospital

The team at CH Systems is currently on contract at the Royal Chelsea Hospital – one of our most prestigious projects to date. We won a tender that commissioned the following:

1.Freezing and Enabling work
2.Plant room installation and pipework
3.Below ground pipe Gas pipework

The work includes the creation of two small boiler rooms (within existing plant rooms), which are required to supplement the existing heating system during periods of high load. As one might imagine, this is extremely important within the context of a hospital environment.

As part of the ‘enabling’ that had to be carried out prior to commencing work on the boilers, we had to cut into the existing primary pipework within the plant rooms in order to make our connections to the existing system. With a building of this size, draining down the pipework is not an option due to the length of downtime and inconvenience this might cause to hospital guests, so we froze the pipework in the West and East plant rooms (with the help of an expert Pipe Freezing Service) and used liquid nitrogen to stop the flow of water thus enabling work to take place with as little downtime possible.

Because we were under pressure to get the system up and running as soon as possible, we opted for a number of prefabricated sections of 3-inch and 4-inch pipework (on which our welders did an excellent job) that we joined to the existing system without issue. Not being able to thread pipework or weld anything into place, we used the Viega Megapress system, with support from Paul Burkett (this being our first instance of using the megapress), enabling us to press onto medium and heavy weight pipe thus dramatically speeding up the entire process.

We’re still in the midst of completing the project but check out the pics below to get an idea of the the work explained above…and watch this space for further project updates.

Small space boiler installation  – MRM Worldwide

Sometimes, the installation process is like a puzzle – figuring out how to make the best use of the available space in order to ensure a system that is as cost-effective, safe and efficient as possible. The team at CH Systems was recently commissioned for a boiler installation by MRM Worldwide, which turned out to be an interesting challenge.
The work took place in a ‘package plant room’ that was built and assembled off site then craned up into place and essentially “plugged in”. The seven Keston boilers populating this very tight space had reached the end of their serviceable life and needed replacing but due compact nature of this plant room, our only option was to fit four Keston Heat 55 Boilers in the space left when we removed six of the original Keston 170 Boilers.

Keston’s Heat 55 Boiler was the perfect option for this type condensed space as it has been designed to be light weight and offer flexible installation solutions. Every component within the Heat 55 has been carefully selected to ensure maximum reliability and longevity. With simplicity in mind the boiler features a large back lit screen and simple button controls, allowing the user to get the most from their new boiler installation.

Also included in the installation was a compact, fully integrated Flamco Pressurisation unit – again, perfect for a small are. Have a look at the pics below to get a sense of the space we were working with:

Top tips for business gas safety

According to the Gas Safety (Instillation & Use) Regulations of 1998…

“It’s the duty of every employer or self-employed person to ensure that any gas appliance, installation pipe work or flue installed at any place of work under their control is maintained in a safe condition so as to prevent risk or injury to any person.”

As a business owner, you’d have known this – per logic if not per regulation.  A reminder is never a bad thing though, right? And it’s good to know that the law takes our safety seriously. Keeping company employees and premises safe includes a couple of simple steps, check it out:

  • Appliances should be serviced annually
  • All services, installations and repairs should be carried out by a Gas Safe registered engineer
  • Keep a record of any work that’s done
  • Replace your CO alarms every five-to-seven years
  • Consider a service plan if your business relies on heating or gas appliances.

A business gas safety check is an inspection or service of your commercial gas appliance or boiler by a Gas Safe registered engineer, who will check your appliance or system to make sure its running safely and efficiently. This should be done on a yearly basis, and will also include:

  • A safety inspection of your metre and all visible pipework
  • A tightness test on your entire gas installation
  • A boiler service
  • A Gas Safety certificate once the inspection is complete.

High pressure gas purge – MCSBS

In order to ensure the efficient and effective functioning of a Hamworthy Gas Fired Water Heater with an onsite gas carcass running at 35mb (not common place), the CH Systems team opted to decommission the gas line to fit a local Governor serving the water heater. Once the pipework modifications were carried out we returned the pipework into service and conducted a tightness test as well as a purge back to Natural Gas.

Decommissioning, tightness testing and purging are carried out on existing or new gas pipework installations to ensure that the industrial and commercial gas pipework is safe for use, or continued use, and will not be rendered a hazard or cause an unsafe situation. The high pressures produced by this particular system required both experience and skill on the part of our engineers. See the below pics for an idea of what the job entailed:

Boiler Chemical Clean

We always enjoy repeat work with our regular clients and a recent commission to carry out a chemical clean on nine Hamworthy Wessex 220 M Modular boilers for one of our regulars in Luton was no exception. The boilers were under-performing in efficiency, having not been cleaned in some time and the team at CH Systems was happy to revitalise these massive pieces of machinery to proper working order.

The heat exchangers within these boilers are in excess of 100kg and, as such, required lifting equipment to safely handle them. We’re always up for a challenge, and all nine boilers were cleaned over the course of 2 weeks and put back into service for our client in the most timely fashion possible.

To get maximum efficiency from your boiler, no matter how big or small, it’s important to schedule regular (yearly – as per industry standard) maintenance checks; this will enable your heating professional to fix any problems before they escalate, and end up costing you more money!

When to call a professional plumber

There are times when the handyman at work will be able to fix a clogged toilet or a slow drain with a plunger and a little elbow grease, and there are also times when he won’t. Sometimes, problems will require a professional in order to avoid major property damage and extortionate costs; the question is, when? Here are some of the most common problems that are likely to require a call to your go-to plumbing service:

Low water pressure – when water is trickling instead of gushing, you probably need a plumber. Pipe obstructions, city supply issues or poor pipe design can all play a part in low-pressure fixtures. A plumbing professional will be able to recognise the source of your problem and provide an appropriate solution.

Leaking pipes – are not usually a big deal but can be a costly nuisance. Leaks usually happen at joints and typically require permanent plumbing repair that may mean replacing a length of pipe or its fittings; a job best done by a pro.

Blocked drains – plungers and a little muscle can sometimes do the trick when it comes to a minor blockage but it’s not uncommon for debris to cause to clog the pipes, requiring an expert to fix the problem.

Running toilet – there’s nothing more annoying, in an office (or in life), than a toilet that doesn’t work properly. Running toilets (that never seem to flush effectively and take forever to refill) could be the result of a silent leak, which could lead to higher water bills if not dealt with.

No hot water – never good in an office, especially for the staff who have cycled in to work and need a quick shower to start the day! This is usually a result of a failed water heater…but whatever the source of your water heater’s failure; it’s a good idea to hire a plumber or technician to handle the job.

Dripping taps – washers form a water-tight seal, preventing water from pushing its way through the pipes and out of the tap; these washers can become stiff, torn or dislodged, allowing a tiny trickle of water through and creating an annoying drip…drip…drip. A plumber has the specialised tools required to fix this type of problem with relative ease.

When you’re running a business, spontaneous costs can be pretty inconvenient but more inconvenient is spending more money on a problem that could have been solved quicker and earlier, had you called a professional sooner.
