New Worcester Bosch Greenstar Ri in Oxted, Surrey

Rust, Rust and Rust The Energysaver was one of Glowworm’s early efforts at a high efficiency boiler.  Like the ill fated Potterton Envoy and Baxi Barcelona, the Energysaver had the lifespan of a prawn sandwich.    Although manufacturers like Archie Kidd had perfected the art of condensing boilers decades earlier, the mass market British boiler industry left their designs to the last minute and used their loyal customer base as a test bed.  Glowworm was snapped up by Vaillant (a leading German boiler manufacturer) over 5 years ago and the Energysaver model was quickly consigned to history and replaced by European designs.  […]

New High Efficiency Floor Standing Worcester boiler

Worcester Bosch have recently brought out a new range of floor standing boilers.  Designed to replace the inefficient Potterton Kingfisher, Ideal Mexico and other floor standing boilers of old, this new unit looks similar, and in most situations can be fitted directly in place of the original. Our customer lived in a large house in Banstead, Surrey.  Being a retired doctor of engineering,  he knew his old 125,000 BTu Potterton Kingfisher was not going to last much longer, and rather liked the idea of swapping a 65% efficient boiler for a 91% efficient one. He especially liked the idea of not […]

New Worcester Boiler in Beddington, Croydon

This unit replaced an old Ideal Standard cast iron boiler in a storage room.  The Ideal Standard WM series unit was a bit long in the tooth, and was probably only 65% efficient. We specified a 12Kw Worcester Bosch Ri replacement, which can achieve an efficiency of over 90% when used on a like – for – like basis. The Worcester was mounted in a similar position to the old unit, but first we had to brick up the large flue aperture remaining from the previous boiler.  The next door neighbour had recently had their boiler replaced by another contractor, […]

Heat Pump (air to air)

Our customer had already fitted a Hot Water & Central Heating installed Hometronic system in his main residence, complete with an accumulator boosted hot and cold water system. He has a beautiful wooden barn building, separate from the house, which he uses to work from home. We discussed using a combination boiler and radiators, but the sloping eaves design of the barn and the various space constraints within meant that radiators would not be ideal. The barn, having a roof room with a vaulted ceiling, gets very warm in the summer, so we recommended fitting a heat pump. Historically, a heat […]

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 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 […]

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 Worcester Bosch oil combination boiler

This customer had a very old Worcester combi in their petite kitchen, in a rural location near Merstham, Surrey. The old boiler had been installed with the flue too close to a window, and in addition some leakage had resulted in damage to the floor. We suggested relocating the new replacement outside, so more space could be liberated in the house.  Also it meant that the boiler flue ‘plume’ would not be immediately under the kitchen view of the garden. A new Worcester Bosch Greenstar oil combination boiler was fitted on a concrete plinth under an old carport, to the […]

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.

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.
