End of terrace in Sevenoaks with water flow issues

We were called to an interesting refurbishment in Ide Hill, near Sevenoaks, Kent.   The house was in a very rural location at the end of a terrace of four victorian cottages. We couldn’t take any decent photos of the house at the time of the job because it was covered in scaffolding! The property was being updated and renovated;  as space was tight the customer wanted to remove water tanks and the hot water cylinder from the house and at the same time replace the old oil boiler in a shed on the other side of the entrance pathway.

No place like home, EvoHome

This is a post closer to home.  In fact it is my home! Our house in Edenbridge, Kent is heated by an Archie Kidd (Thermal) Ltd oil fired boiler, and has around 26 radiators.  It was built in 1894 and heating it is an expensive business, because our insulation is hard to improve. In 2005 we installed Honeywell Hometronic.  This is a system that uses remote control radiator valves to divide the house into 16 areas of controlled heating.  This enabled us to reduce the heating level in rooms we weren’t using in the day, but warm them in the […]

New model Worcester-Bosch Danesmoor external

In our previous post we described the unfortunate experience of my brother in law, in Nantwich, where he had a Worcester-Bosch Danesmoor installed by a registered installer, and got a particularly shoddy job.   This post is hopefully a better example, because it was one of our installations! Our customer is in the Gatwick area (south east England) and lives in a detached chalet bungalow. He had an older Worcester 14/19 internal oil boiler, which had developed a problem which rendered it beyond economic repair.  It also necessitated removal of a granite worktop whenever anything significant required attention, so our […]

Large old listed country house – 155Kw boiler system renewal

We’ve just replaced the boiler plant in a very large country residence in Sussex (July 2013). The old oil fired Worcester Bosch system heated the house, which was mainly comprised of 60 yr old radiators and large bore steel pipe, as an entire single entity without any zone control.  The oil bill (no mains gas here) was £12K per annum. Our customer looked at a number of options, but liked our approach best.  Our unique proposal was to improve the efficiency of the boiler room by using weather compensation and load sharing – reduce consumption of oil and increase comfort, […]

Oil fired 1969 warm air heater replacement in Chatham, Kent

We were asked to look at a very cold house on the outskirts of Chatham by an older gentleman, whose heating had failed.  The warm air system dated back to the mid 1960s, when the house was built.  Spares being no longer available, the warm air unit had given it’s last and the house was freezing. The hot water system was similarly antiquated, using a vapourising pot oil burner in the utility room to heat a conventional hot water cylinder upstairs via an indirect water coil. There aren’t many options when it comes to domestic oil fired warm air.  Lennox […]

Outside boiler in Kent

Hello and welcome to our latest post.  This job, undertaken during the Olympics, was on a listed property in Four Elms, Kent.   It is an oil boiler (we seem to be doing lots of these at the moment), a Perrymatics Jetstreme MkII, and the owners of the property fancied updating it with a new high efficiency model, and relocating it outside the property. As usual, we were pleased to oblige!  The Jetstreme was removed from the rear office area creating significantly more room, and also making the house quieter.  The old boiler was an ‘open flue’ type so there […]

Replace oil AGA with new Heritage cooker

In my mind the AGA is a great cooker.  It works on the principle of a large heavy mass full of heat, if you stick something cooler and smaller inside (such as the Sunday roast), heat simply transfers from the large heat mass to the small one.  There is virtually no air movement in the oven so flavours stay intact, food stays moister. The design is thanks to a 1920s Swedish inventor, today it is still very similar to the original.  Which means that energy efficiency is appalling (that is my description, AGA use the words ‘surprisingly economical’).  An oil […]

An unusual warm air job using a Bosch Greenstar boiler

This is a house in a remote location near Maidstone, Kent.  Some 200 years old, it was bought in a semi derelict condition over 35 years ago by the present owner, whose late husband was an architect.  He remodelled and partially rebuilt the house, retaining all the period charm, but incorporating modern upgrades, including adding ducted warm air heating. The heating plant room was around the back of the house in an external cupboard, and the original warm air unit (oil fired) was replaced around 14 years ago by a local contractor.  This 1990s unit, a Lennox oil fired cabinet, […]

Kidd boiler removed

The venerable Kidd Very High Efficiency (VHE) boiler is one of my favourites.  Designed for Archie Kidd’s personal use in 1959, and then productionised in 1982, it has been the forerunner in condensing high efficiency technology in the UK for 30 years.  Forget all the stories you hear about the Vaillant this, or the Worcester that, or the Baxi Bla Bla, the Kidd VHE was the first and last, the design is still current today, and 98% unchanged. OK, so you’ve got a Potterton Kingfisher and it is still going after 25yrs?  Not a big deal.  The Kidd was available […]

Oil boiler goes up chimney

OK. so we’ve covered a Worcester -Bosch gas boiler using an existing chimney, so here’s an oil boiler version.  Sticking with Worcester-Bosch, this one is a Camray Greenstar 18/25 Utility model. We’re in a remote area south of Dorking, Surrey, accessed via a long farm track. The property had a Trianco oiler, made around 16 years ago, with a leaking heat exchanger.  This is the end of the road for an oil boiler, because the heat exchanger is the whole metal frame of the boiler. Trianco have always been a budget boiler manufacturer, and have, as a company, seemingly lurched […]

The job was very professionally undertaken on time and budget with no adverse issues raised. Customer satisfaction appeared to be a high priority.

Martin, Kent 25/04/2017

Excellent

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…

Started and finished on time. Workmanship as good as ever. prices reasonable.

Peter, Surrey 24/05/2016

Smart solution, neatly implemented

Great technical solution to the tricky replacement of a 1980’s warm air unit. Starting with a clear and comprehensive quotation. Careful and tidy installation with minimal disruption. Excellent communication throughout the work.

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.

Stephen, Kent 19/06/2015

Knowledgeable, friendly and efficient

HW and CH knowledgeable, friendly and efficient company we would certainly recommend them.

John, Kent 01/06/2015

Reliable & professional company

Hot Water & Central Heating responded very promptly & installed a new boiler in a quite awkward location. Very helpful

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

Diligent & Efficient

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.
