Replacement for unreliable Ideal Combi
Our customer lives in Oxted, Surrey, and had an Ideal combination boiler initially installed under the Warmfront scheme around 7 years ago. Not uncommonly for this model, a plethora of parts had been fitted over the years to try to keep it working, but without any success. Some of the old parts were still on site. We recommended fitting a new Worcester Bosch Greenstar 28i Junior condensing combination boiler. This new unit easily fitted inside the old boiler cupboard, and was considerably quieter than its predecessor. This was quite an easy job (makes a change) because all the pipework […]
Floor Standing Potterton out, Bosch in
Completed in early April 2009, this customer’s house, on the Sanderstead/Purley borders (Surrey, UK) had an aged Potterton boiler removed and changed for a new wall hung Worcester Bosch 24Ri. The new boiler was a third of the size and weight of the old unit, but had exactly the same power output. The old cast iron unit had been very reliable, but extremely wasteful of gas. Old floorstanding cast iron units rarely give an efficiency of greater than 65%. A new high efficiency boiler will achieve around 90% efficiency. In other words, comparing the old boiler to the new one, for […]
Large Vaillant Combi in loft
Our customer owns a terraced town house in London SE19. He had considered a solar hot water system in the loft, as he wanted to minimise his family impact on the environment; with solar hot water it is important to maximise the hot water storage, or you quickly run out of solar heated water and have to use the boiler. Unfortunately, the design of these properties leaves a low headroom in the loft, restricting the size of cylinder, and there is limited weight capacity for large volumes of water. So, instead, he decided to fit the Vaillant ecoTEC+ 937 hybrid […]
Large Worcester combi hidden in loft
The house, located in Smallfield, near Gatwick, had a conventional heating system with a copper cylinder, water tank etc. The old boiler had been mounted in a bedroom cupboard, which is always best avoided for noise reasons. We fitted a new Worcester Bosch Greenstar 37CDi combination boiler in the loft space, on a custom made partition. The Worcester boiler has a high hot water flow rate, which uses over 37Kw of power. This necessitated a new gas pipe, which we connected via the existing external recessed meter housing and routed into the loft space. The new boiler system rendered the […]
Low pressure water solution in Crystal Palace
Our customer lives in an area of Crystal Palace where the water supplier has in the last 12 months reduced the pressure in the mains. This has resulted in a pressure just above 1bar on the lower ground floor; this house is on 4 stories and there are bathrooms on the 2nd and 3rd floors. The result was that the bath took ages to fill, the shower on the 3rd floor could not be used, and the shower on the 2nd floor was poor. Protests to Thames Water from most of the residents in the immediate area did not result […]
Better showers = unvented cylinder
Our customer in Purley had a boiler fitted by Hot Water & Central Heating in 2005, and was in the process of having a bathroom refitted. Their old gravity water system cylinder was in the way of a new shower enclosure. We worked alongside their bathroom installers (Visions) to swap over from a vented bathroom setup to a new unvented cylinder in the loft. Our customer is a retired chemical engineer, and he specified one of the first Vaillant weather compensated heating systems when we originally installed his Vaillant ecoTEC 630 boiler in 2005. Naturally, he decided to […]
Back Boiler in the skip
There was a time when a backboiler (a gas fire with a hidden cast iron central heating boiler hidden inside the fireplace) was the height of fashion. Unfortunately, the front fires now look dated, but more importantly, the bit at the back is usually only 60%-65% efficient in its use of your expensive gas. Our customer in Pembury (near Tunbridge Wells, Kent) had decided it was time to invest in a new energy efficient boiler, and from the 3 quotes, he chose Hot Water & Central Heating for the task. The boiler was to be moved from the lounge to […]
Warm Air out, new radiator system in
The house, located in leafy Caterham, Surrey, was built in the early 60s and was heated by a warm air ducted system. In common with many installations of this period, some rooms had no direct ducting and relied on leaving the doors open. Our customer wished to use the large cupboard currently occupied by the warm air system for storage. They also wanted a mains pressure delivery of hot and cold water, and minimum wastful stored hot water. We suggested the new Worcester Bosch Highflow 440CDi. This is a floor mounted unit, recently updated from the Highflow 440. With […]
New Vaillant System boiler in Coulsdon, Surrey
Our customer had an old Glowworm boiler which was in a position preventing a planned extension to the house. HWCH Ltd were recommended by another customer, and we suggested replacing the boiler with a modern Vaillant ecoTEC 630 system boiler. The Vaillant ecoTEC+ 630 is a 30Kw boiler (102,000 BTu output) with an integral 2 speed pump, all mounted in a modern near-silent enclosure. We give 5 year warranties on our Vaillant boilers, which, along with the recommendation, no doubt helped win us this contract. The customer had originally carried his own central heating installation over 20 years ago, and a […]
Replacement water system in cellar for multi bathroom residence
ºOur customer has a large 3 storey Victorian detached property in Dulwich. In common with many houses in this area, an old gravity fed hot and cold water system using loft tanks was employed. Our customer wished to gradually update his house to new mains pressure fed bathrooms, using European high pressure taps, and wisely didn’t fancy the prospect of shower pumps. He also wanted to make use of the loft space currently occupied by the large water tanks, and remove the old copper hot water storage cylinder on the 1st floor to make room for another shower. Our brief was […]
