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 […]

Improving water supply and Acorn heating pipework issues

Our customer lives in a remote rural location near Warlingham, in Surrey, UK. They asked us to provide a proposal to update their old Grant boiler. Interestingly, it had rotted through a few years previously, and their heating technician had located a comparatively healthy heat secondhand heat exchanger in Cornwall, which he had successfully fitted. The ladder type steel radiators suffered from perpetual air and some had stopped working, others had lost the upper sections and were partially cold, something which venting could not cure. I was intrigued because although the system was fitted with a header tank, there was […]

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 […]

New model ATAG combi, runaway installer and Evohome zoning using OpenTherm

We’ve been installing commercial sized ATAG boilers for some time, in fact, you will find some others on this blog. ATAG have recently relaunched their domestic offering in the UK, and now offer 10 year warranties and 24hr technician support.   ATAG are a premium brand boiler manufacturer from the Netherlands, although a stake is now owned by Ariston MTS Group. Our customer had selected an ATAG IC Economiser 39, which is a combi boiler augmented with ‘designed at birth’ flue gas heat recovery (rather than tacked on afterwards like most other manufacturers), and reputed to be the most efficient boiler […]

Worcester-Bosch 1 Keston 0

For this case study, we find ourselves in Oxted, Surrey.  We like Oxted, because it is a lovely, virtually unspoilt town (if you exclude Morrisons) full of coffee shops and yummy mummies.  I suppose it is similar to Sevenoaks with all the good bits squeezed into a smaller area.  It is also very close to Hot Water & Central Heating Ltd HQ, so we get a lot of projects there. A larger house, this had a Keston C55 boiler and a significant number of radiators.  The Keston boiler had been unreliable (no surprises there) so we suggested a Worcester-Bosch alternative. […]

A new Worcester Danesmoor, MultiCalor Warm Air, Radiators, Water pressure boosting…..

Today we are in a rural property in the Edenbridge/Tonbridge area of Kent. Our customer has recently moved back to the UK from working abroad.  He has bought a detached house in the middle of the Kent countryside. The subject of an extensive makeover in the last 20 years, this property had a Lennox oil fired warm air unit in the cellar, a Worcester standard efficiency boiler in the external cupboard, and a conventional hot water system. The warm air system was around 20 years old, and covered the two reception rooms , kitchen and hall areas. It was very […]

William Pitt the Younger’s house

The focus of our case study is a listed building in Westerham, Kent, which was once the residence of William Pitt the younger. Westerham is a small town steeped in history, and features Chartwell, home of Winston Churchill, Downe House, home to Charles Darwin, and Squerryes Court.  Chevening, the deputy prime minister’s estate, is just down the road. Featuring timbers that are believed to date back to the 13th century, in more recent times William Pitts’ former house has been an upmarket restaurant, and an Indian fine dining eaterie. The present owners purchased the property in a state of dilapidation, […]

Anne of Cleves’ house gets an upgrade

Readers of this blog will know that we regularly get commissions from owners of listed properties for their heating upgrades. Today, we are in a Grade 1 listed country house in Ditchling, Sussex, UK, dating back to the 16th century, or possibly earlier. Henry VIII was believed to have bought this house for Anne of Cleves;  later residents included William Pitt*. *William Pitt will also appear as a case study for our professional services shortly! In more recent times the house was owned by a radio and TV personality;  our customer has recently moved in and we were engaged to provide […]

Keston boiler in cellar removed, heat store in basement, accumulator, Evohome….

This is a house in a fashionable area of SE London.  Like may Victorian houses, it’s a lot bigger on the inside than first appears from the outside. A big driveway in London is always a bonus. We were asked to provide a quotation to replace a typically troublesome Keston C55 boiler (55Kw) in the basement.  Our customer had experienced numerous breakdowns ever since it was installed in 2004, in fact, I recall them saying that it had never survived a winter without a repair visit. If you have a large Keston, you probably know the story only too well. […]

Complex house heating system of the future (in 1998) gets updated

For this case study, we are in Ealing, West London. Our customer rang us to say he had inadvertently bought a large house with a woefully complex heating system around 8 years ago.  The first time he viewed the house, it was perfect – but they never went into the garage.  On the second visit, he popped his head into the garage area, and found it completely full of commercial plant, and a ambient temperature of over 30C. Since then, many a central heating specialist has escaped having seen the garage;  apparently they are brimming with confidence until the door […]

Truly excellent, as much technically as aesthetic: clean, prompt, going well beyond expectations.

Nicholas, Kent 14/04/2017

Commercial plumbing

A small to medium sized company capable of installing & maintaining a highly technical modernisation of our heating & h/w systems. The planning, execution & result was truly ‘excellent’.

A J, Surrey 04/04/2017

Very knowledgeable

We needed a replacement boiler & Simon talked us through the options, which manufacturer & what size to go for & saw through the installation, not leaving until he was satisfied that all was in order. All in all very, competent and professional.

Stephen, Kent 16/02/2017

Highly recommended

Not the cheapest but very knowledgeable which gave me confidence that the job would be well done and correctly done. I was not disappointed.

Geoffrey, Kent 06/02/2017

Good standard of work with an ongoing commitment to customer satisfaction

This firm installed a 12 zone Honeywell Evohome central heating and hot water control system for us in October 2014. The quotation was clear and detailed, and the price reasonable. The installation work was personally overseen by the boss, Simon, who also set the rather complex (but powerful) wireless control system to work and gave clear advice on how to get the best from it. He had in-depth knowledge and experience of the control system that is probably second to none. The firm also installed and connected to our boiler a plinth fan heater nicely hidden under a kitchen cupboard Read more…

Martin, Surrey 21/03/2016

Clean + tidy

HWCH installed our boiler a few years ago and have looked after it ever since so I was happy to leave them in the house unaccompanied. We came home to find the installation complete and no mess or trace they had been.

Bryan, London 15/12/2015

Prompt and efficient. Very professional.

My son recommended this firm as I was very apprehensive about having a new boiler. Mr Davies was very clean and helpful and explained everything. The two men who did must of the work were efficient, polite , clean and considerate to me . As far as I can tell I have an efficient job carried out in one long day which helped me.

Jean, Surrey 19/11/2015

Very good job – as always

We have used the company for many years for 2 rental properties & our family home. We cannot fault them.

Jerry, London 27/05/2015

Professional & efficient

I have known HW & CH for several years. They installed two large boilers in a church and hall and maintain them annually. I gave recently used them at my home where they did a very clean, neat and efficient job. Supplied excellent product and were very professional.

David, Kent 16/01/2015

Simon of HWCH takes his job very seriously but is a pleasure to deal with. He assessed our (complicated) situation carefully, recommended the right solution and carried it out promptly and efficiently.

Jay, London 15/01/2015

Expert & professional installation

An intimate knowledge of a rather complex Honeywell Evohome heating control product, combined with an excellent installation crew on the day resulted in a very satisfactory installation. Some tricky rerouting of underfloor pipework was accomplished without fuss, mess or extra charge, highly recommended.

Richard, East Sussex 04/07/2014

Very impressed

Very impressed with work rate and efficiency. Would have no hesitation in recommending them.

Neville, West Sussex 16/03/2014
