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 […]
There are times when it would be nice to relocate everything outside, giving more room internally. Our customer, near Ashford, Kent UK, had already engaged us to fit a warm air unit in an outside cupboard in 2013, using a high efficiency Lennox G61MPVT condensing unit. This has performed admirably, so when a water heating upgrade was required, he turned to us. As things stood, the hot water was heated by electrical immersions and stored in a cylinder on the ground floor, fed by a water tank in the loft. Our customer wanted mains pressure hot water on demand, […]
For this post, we are in Fetcham, in the area of Leatherhead, Surrey. Our customer had a 1970s house that has been comprehensively updated, including a significant extension which was built around 12 yrs ago with radiators. The existing part of the property retained the original warm air heating, in this case using an old Lennox G8 unit under the hallway stairs. Hot water was provided by a conventional cylinder, this was heated by the boiler being used for radiators, a Baxi Solo 3, in the garage. The warm air unit had been the subject of various warning notices over […]
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, […]
Our customer has recently bought a property in the Esher area. Built around 25 years ago, it was heated by two separate Johnson & Starley warm air heaters, one per floor. For hot water, a 295 litre direct gas fired AO Smith cylinder was installed upstairs. There was also a large gas hob and a gas fire. When we totalled up the load for all these appliances, it was around 92kW. This would have been fine, apart for two key problems. The first is that the property had a standard domestic metered supply, which has a maximum design load of […]
Our customer had an old warm air unit, using an open flue chimney system. This was removed and a new Johnson & Starley ‘Economaire’ unit installed in the same position, complete with an internal water heater. The Johnson and Starley standard product has an inbuilt mechanical programmer for central heating and hot water timing. At our customer’s request, we fitted a remote digital 7 day timer to the Economaire, for more flexibility in control.
Our customer had an old warm air unit using an open flue system. Warm air is amongst the most efficient methods of heating a space, and most homeowners with a warm air system would not have anything else, especially radiators! Warm air was very popular from the 1950s to the late 1980s in the UK, with over a million installed at one point. However, they have gone out of fashion now and new units are only installed as replacements, which brings us to our customer in Bookham, near Leatherhead, Surrey. The old unit used to use a conventional flue, that […]
