Sainsbury’s Ashford

CH Systems recently carried out a pipework installation to two Air Handling Units, in Ashford for a major supermarket chain. The works involved upsizing the heating pipework to 2 of the roof mounted AHU’s. The coils on the AHU’s were replaced and the units, themselves, were ovehauled, at the same time that the pipework was being installed.

All the heating in this store is generated by air-source and ground source pumps.

All the pipework on this site was Geberit Mapress and due to the location, of the works, we carried out all the crimping with a Novopress XL pressing tool. This tool is cordless and enabled us to carry out the installation in a very timely fashion.

We’re really proud of how this project turned out. If you have any questions, please do contact us directly.

Louthus Romford

CH Systems were recently commissioned to assist on a very challenging project. The project involved a block of apartments directly above a parade of shops, with the plant room above the stair well. There is a pair of Vaillant boilers serving a Vaillant Buffer vessel which then in turn serves the district heating scheme providing LTHW to the Heat Interface Units in each flat.

The primary pipework required modification from the boilers to the buffer vessel as there was not sufficient flow. The secondary pipework also required modifications to ensure we got the required flow rates.

Our team managed to complete all the works with only one day of down time to the tenants and with little disruption.

Midsomer Norton

CH Systems recently carried out a Plant room upgrade in Midsomer Norton.

We removed an old floor standing shell and tube boiler, which was fitted with a still functional Nu-Way burner. We also removed a gas fired Andrews water heater and Stockvis Domestic hot water plate exchanger.

As you can see from the pictures below, it is extremely important to inspect flues during services as the inner wall of the flue had completely collapsed and was completely blocking the flue way.

These appliances served a Leisure centre so we had to maintain services for the duration of the works. We fitted 4no Remeha boilers complete with frames, low loss header and mixing pot which then goes out to feed the system. The LTHW system was installed in Geberit Low carbon steel Mapress and the gas was fitted in Stainless Steel. We also had to pipe up the new air handling unit which was replaced as the previous model had no heat recovery option.

Overall this project was completed punctually with a minimum of down time to the centre and they should soon see the benefits of a much more energy efficient system.


Walthamstow SSL

We recently carried out a Plant room Upgrade for a National Supermarket Chain in Walthamstow. The works comprised of fitting 2 new Hamworthy Wessex ModuMax mk3 boilers alongside the existing Hamworthy boilers.

Our welders had to fabricate a number of spool pieces to enable us to connect to the Imperial Table D flanges. We also had to fabricate a 6inch header to which all 4 boilers then connected on to. The gas run on this installation was all carried out in 108mm Geberit Mapress Stainless and was slightly challenging as we had to run this on the underside of the first floor slab, this was all carried out on a SkyJack SJ19 which greatly helped in reducing the installation time.

The heating coil that serves the shop floor air handling unit was also changed over during these works and we’re happy with the finish of this project.

Old Ship Hotel, Brighton

In December 2017 we attended a small, but interesting, job at the Old Ship Hotel in Brighton.

We were contacted by the on-site maintenance team to repair a leak. The fault originated from a leaking 6-inch brazed fitting which was not repairable. Our Engineers fabricated and replaced a new section of customised pipe including two tees and Straub Couplings.

The old pipework was damaged and corroded, due to the leak, so we replaced this with brand new copper pipework. We carried out the works during daytime hours to minimise the disruption to the hotel. Our freeze team attended site and used liquid nitrogen to freeze the pipework.

We are really proud to have been able to rectify the faults with no effect to their business. Below are some images to show what we were dealing with and what our work looked like once we’d completed.

Southside Shopping Centre, Wandsworth

CH Systems were instructed to refurbish the public toilets at Southside Shopping Centre, Wandsworth in June 2017.

The scope of work involved mechanical services, including validation of existing services, stripping out redundant services, new supply and extract ductwork. We also installed new extract twin fan units, diffusers, exhaust fans, Nu-Aire air handling units as well as supply and extract ductwork throughout.

Public Health services provided included validation of existing hot water cylinders and booster set, installation of new domestic hot and cold water services from the incoming hot and cold water services feed using Yorkshire copper and end feed fittings.

Our experienced Engineers installed new gravity soil and waste pipework to connect to existing vent stacks. We used Geberit UPVC soil pipe and vent fittings. Lastly, we chlorinated water service pipework and tested all services.

The Client was pleased with the outcome of the refurbished toilets which we completed on time and within budget. All the works were completed within the latest Building Regulations L2B and environmentally sustainable.

Major Supermarket, Pimlico

In October 2017, we were instructed to carry out works for a major supermarket based in Central London.

Our experienced engineers stripped out 4 boilers and replaced these with Ideal Tormax 100 boilers, as well as installing a Megaflo 500 litre commercial hot water cylinder.

We used materials including Gebrit Mapress pipe and fittings, as well as Grundfos twin head pumps which are more reliable and energy-efficient.

Low carbon steel was used for the heating system which is not only better for the environment but is proven to be a better product due to its corrosion resistance. Stainless steel was used on the gas supply. By using ideal frame headers and the Gebrit system, the installation time was substantially improved in comparison to using traditional materials.

Project Dragonfly

CH Systems has been involved in Project Dragonfly, down in Erith, and we recently completed the installation of all pipework in the fourth Ocado Customer Fulfilment centre. The warehouse sits on a circa 40 acre site close to the River Thames. The warehouse unit when complete will have 560,000 sq ft of distribution space with offices totalling 27,857 sq ft. The warehouse unit will have 72 dock and 16 level access doors, and room for 326 cars and 287 HGVs.

Within the scope of works we carried out the following:

  • Boiler and plant room pipework installation including 2no Ideal Imax Xtra floor standing condensing boilers and 2no Andrews MAXXflo gas fired water heaters.
  • Within the plant room there was also 4no Air Handling Units which were fed off the heating circuit.
  • All of the heating pipework was installed in Low Carbon Steel Mapress all the way to 108mm OD in excess of 1200 meters.
  • All of the domestic pipework over 2000 meters was installed in Copper Mapress up to and including 54mm.
  • All the second fix of 60 toilets, 6 showers, numerous hand wash basins and 4 squatting toilets.
  • Over 450 meters of Geberit HDPE soil pipe was installed to serve all the waste outlets on site.

Once again we received a large amount of project support from our suppliers, including BSS and Smith Brothers Stores, as well as Geberit who supplied all the pipe fittings across the project.

In summary this was the largest project we have completed to date, and we’d like to thank our team of fitters, as well as the upstream management for their hard work, ensuring this all ran smoothly.

139 Kensington High Street, W8

CH Systems recently completed a Plumbing, Heating & Ventilation installation in Kensington, London W8.

We have installed a communal Scuba tank (booster set) provided by Duty point to provide boosted mains water to each of the of 9 apartments.

All of the apartments incorporate Nuaire extraction units for the kitchens/bathrooms & Ariston boilers/water heaters providing the heating and hot water throughout.

All the pipework, for the heating and domestic services, has been installed in Uponor PEx and all the Soil and Waste pipework has been installed in Geberit HDPE, using these materials has given us a system that we can trust and give us a trouble free, high quality installation.
