Grade II listed building condensing boiler using chimney

Today we are in a house in a beautiful part of the Garden of England, in other words, Kent. The house is in a small village reminiscent of the one filmed many years ago for a Hovis advert, with cobbled streets and high pavements. Our customer had bought a house with an old Potterton Osprey light commercial in the cellar, and British Gas had said that many parts were no longer available. Other contractors had suggested the only options involved siting a new boiler on an external wall; this would have resulted in lots of unwanted visible pipework but also […]


Remove Ideal iStor boiler and fit super new Viessmann and Fabdec system

We’ve published a similar story here before, which is one of the reasons why our customer in this case study called us. He recently bought a relatively new property (2011) with an Ideal iStor on the second floor, it wasn’t working properly, and he had been advised that it had been a money pit since virtually day one. The other reason he got in contact with Hot Water & Central Heating Ltd was that he had used us for boiler installation before, in this case around 11 years ago (not in this house!).  A refreshing number of our early customers […]


Viessmann light commercial in Edenbridge

Pyser Optics are a long established company in Edenbridge, specialising in equipment for  broadcasting and defence markets across the World. In fact, in a previous job, I used to order Broadcast TV camera lenses from them!  Small world, they say. We were asked to specify a replacement for a 96Kw output SIME cast iron sectional boiler, which had been classed as unsafe.  It was used to heat the main administration block of Pyser. Our heat calculations suggested that an 80Kw boiler would be more than adequate. We provided Pyser Optics Ltd with two options;  a cheaper solution using a mainstream […]


Commercial boiler Design and Installation at premier Surrey Golf Club

Tandridge Golf Club was designed by the renowned Harry Colt in 1924, and today is judged as one of the top 100 golf courses in the UK. Situated in a rural location near Oxted, in Surrey (UK), it has a thriving membership and is a beautiful course; the main club buildings date from 1928 and have been carefully retained to the present day (unfortunately the first clubhouse burnt down in 1927, exacerbated by the thatched roof). It is popular every day, with golfers seemingly happy to battle in all weathers at all times of the year, perhaps encouraged by the excellent dining […]


Viessmann Boiler upgrade and Honeywell EvoHome

Today we are removing a 12 year old Keston condensing gas boiler (don’t see many lasting that long!) and replacing it with a Viessmann WB1B 19Kw compact boiler.  Our customer lives in Redhill, Surrey, and is what you would call an early adopter, as he understand technology and the benefits it can bring.  He fitted a Trisave condensing boiler in the mid 80’s, then the Keston and now wanted a well made reliable boiler.   Enter the Viessmann!  He can’t believe how quiet the Viessmann is! We are also changing all the controls, fitting a few new radiators, and fitting […]


New Viessmann heat-only in Edenbridge, Kent

Our client lives in our base town of Edenbridge, Kent, UK. The old boiler, a Potterton Netaheat, was in a fragile state, so we recommended replacing it with a Viessmann 100 Compact. It’s a Compact because it will fit inside a typical wall cupboard.  This boiler is Viessmann’s latest small domestic boiler, called a WB1B, and is very well made amongst the competition. Featuring a heavyweight unique stainless steel heat exchanger, with an aluminium front burner plate, this is one boiler which looks like you might get 15 years out of it.  It is simple, but ruggedly constructed. We’d fit […]


Condensing boiler using old chimney stack

This is another installation example of a situation where it is requested that we fit a new high efficiency boiler to an old chimney stack. We are in the town of Sevenoaks, Kent (UK) where there is a 35 year old floor standing Potterton boiler in the breakfast room, using a flue passing inside a brick chimney. We specified a Viessmann Compact WB1B 26Kw unit, with a sealed system chimney liner.  This allowed us to install a room-sealed boiler using the stack for exhaust and fresh air inlet. We removed the old boiler, rationalised the pipework.  The customer then had […]


Condensing boiler in cellar and chimney liner

Over to the picturesque Sussex town of Horsham, where we have a beautiful listed residence in the protected heritage quarter of the town. British Gas condemned the old floorstanding Potterton boiler in the cellar, and they and other contractors suggested that the only solution was the relocation of a new boiler at the other end of the house, involving unsightly pipework throughout. The existing defunct boiler was flued up a very old chimney weaving through 3 floors; we suggested fitting a new Viessmann Compact 26Kw boiler in the cellar.  The existing system was very old, the cylinder was around 60 […]


Kent Church has a new condensing boiler

Our photo shows Dan in contemplation, in the graveyard of St John the Evangelist, in Hildenborough, Kent.  Actually, he’s assisting in a purging operation at the gas meter box. This church, constructed over 100 years ago, was heated by an old 86kW Ideal Buccaneer commercial boiler.  The boiler had a reputation for breaking down in the hour of need (eg: coldest days of winter) and the management team had found the only way to minimise the chances of failure was to have the boiler on in periods of the summer. The heating was controlled by a bewildering set of high/low […]


Major refurbishment in Woldingham, Surrey

Our client has bought a 1960s house in the well regarded village of Woldingham, Surrey, and embarked on a major remodelling of all services and interiors. When finished, the building will incorporate a modern kitchen, and comprehensively remodelled interiors. We have assisted our customer in the selection of the heating system, but they have also contributed much to the specification, including the innovative Jaga Strada ‘low H20’ high efficiency radiators. HWCH will be fitting a large underfloor heating grid on the ground floor, a 46Kw Viessmann 200 series light commercial boiler, accumulator boosted DualStream hot and cold water system, all controlled […]
