Warm Air removed and replaced with radiators
Our client had a three storey town house in Beckenham, Kent. Built in the 1970s, it had been fitted with a Johnson & Starley warm air system from new. Now theres’s nothing wrong with warm air heating, and we fit the latest US Lennox condensing units for the more discerning customers. But in common with many properties of this era, economies had been made with the ductwork, resulting in no direct heating of the third bedroom or bathroom. Our customer had recently bought the property, and faced the choice of many similar households wondering whether to replace the warm air […]
Low flow rate solved for Vaillant 937 installation
Our customer, in Woldingham, Surrey, had recently purchased a property with a conventional tank fed water system. They wished to remove a couple of shower pumps and the water tanks and install a direct fed pressurized water system. The problem was that the water flow rate into the property was around 9-10 litres per minute. There was also a limited space to fit the entire boiler plant into. We had to boost the flow rate as well as provide the new boiler plant, all within a single cupboard. We chose to fit a wall hung Vaillant ecoTEC 937, which is […]
Conventional boiler to combination in South Croydon Flat
Our customer had an ageing Potterton wall hung boiler, which was affected by sludge, and wished to convert it to a mains pressure combination boiler solution. The old boiler and cylinder had been squeezed into a new kitchen conversion, so it was very awkward to access the constituent parts. We removed the old wall hung boiler and cylinder, and fitted a new Worcester-Bosch condensing combination boiler. The hot water cylinder, tanks and associated controls were no longer required in the new configuration, and were scrapped. We cut a neat slot in the kitchen cabinet carcass, which allowed us to achieve […]
Unusual house in Reigate, Surrey, gets unique underfloor heating
This property had an old HarcoPak, which is an integrated hot water cylinder and cold water storage tank, mounted in a frame on the 1st floor. It was heated by an old Potterton Kingfisher 100BF floorstanding boiler, which had been installed with a flue a couple of inches from the rear door and an undersized gas pipe; both of which were contrary to the gas regs at the time the house was constructed, and still are. We removed the Potty boiler, leaving a large hole for the on site building team of Mizon Builders to brick up. We relocated the […]
DPS Heatstore solves loft conversion challenge
The house pictured, located in Croydon, Surrey UK, was being extended into the loft space. The loft tanks for the hot water system and radiator header tanks had to be removed to make way for the new accommodation. Our challenge was to provide a new heating and high pressure cold & hot water system in an 1900mm high cellar, which could replicate the shower performance of the existing powerful pumped tank fed system in the loft. Furthermore, it should support the use of extra bathrooms in the loft area. This project raised a number of challenging problems. We could have […]
Underfloor heating in barn, new external oil boiler, and hot water upgrade in Limpsfield
Limpsfield is a village on the outskirts of Oxted, Surrey (UK). Our customer already has a ‘Hot Water & Central Heating’ installed oil fired cooker range (see our Heritage cooker page above), and was building an outside barn further down the garden. The central heating boiler was an old oil fired unit, which was located in the hallway and could be heard throughout the property. Our customer wanted a new boiler and also wished to convert the water system to a new unvented type. Hot Water & Central Heating suggested that a Grant 3646 outdoor module was fitted, this is […]
Water Mains boost for Crystal Palace house No2!
Having transformed the water supply next door, we were invited to carry out the same task on this property. A TCWS Charger and mainsboost system was fitted, connected to an existing Gledhill Boilermate III heat store. Now all the showers work on all floors. Charger/Mainsboost is a specialised water boosting product which utilises the ruling that water can be pumped from the mains at up to 12 litres per minute. The water authorities are very particular at how this can be done, and in order to get approvals the manufacturer took around two years perfecting the design to prevent any […]
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 […]
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 […]
