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. […]
2nd Vaillant boiler in Peckham apartment
Working on behalf of a Landlord, we replaced a 20yr old Vaillant system boiler in this apartment block in Peckham, South East London. The old unit was beyond economic repair, and our customer wanted the peace of mind a new boiler with a 5 year warranty would bring. We imagine his tenant would be appreciative too. We removed the old unit, powerflushed all the radiators, and dosed the system with corrosion inhibitor. When we connected the new boiler there were problems with the hot water motorised valve in the upstairs airing cupboard. Upon examination the wiring and and the […]
Replace old Potteron Prima with the latest Vaillant condensing boiler
Having installed a Vaillant boiler in a rented property owned by this customer in 2008, we were invited to quote for a new boiler in his main residence, a very nice house near Hurstpierpoint, Sussex, UK. We recommended the Vaillant 428 ecoTEC+ compact heat only boiler. This manufacturer has a unique selling point in that their external flue can be routed to a vertical termination point. Many condensing boiler installations have a nuisance factor in that the steam (or ‘plume’ as we describe it) passes visibly across the house and can be detrimental to the owner’s enjoyment. The Vaillant […]
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 […]
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 […]
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, […]
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 […]
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 […]
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 […]
New Vaillant System boiler in Coulsdon, Surrey
Our customer had an old Glowworm boiler which was in a position preventing a planned extension to the house. HWCH Ltd were recommended by another customer, and we suggested replacing the boiler with a modern Vaillant ecoTEC 630 system boiler. The Vaillant ecoTEC+ 630 is a 30Kw boiler (102,000 BTu output) with an integral 2 speed pump, all mounted in a modern near-silent enclosure. We give 5 year warranties on our Vaillant boilers, which, along with the recommendation, no doubt helped win us this contract. The customer had originally carried his own central heating installation over 20 years ago, and a […]
