Underwater listed building, novel oil flue system

Here we have an unusual case study. It is a listed building in a rural part of Kent, UK, on top of a hilly area. It has a large cellar covering most of the floor area of the house. In very heavy rainfall in 2019, the road (some considerable distance from the house) became flooded, and due to some collapsed drainage on the highway, a very large amount of water gathered in a pond. At some point during the night, the water found its way into a cellar light, smashed the window, and quickly filled the entire cellar, all the […]

Barn conversion near Tonbridge, Kent

Here we find ourselves down a rural unmarked lane in Kent, the site of a large barn conversion. It comprises a two storey hallway, and many original features. Much of the house is already underfloor heated, using an L&K system with around 14 separately controlled zones. What makes this system unusual is the various heat sources used to create the heating and hot water. There’s two fuel burning stoves, some solar thermal on the rooftop, and a Rayburn solid fuel stove. This was all installed by the present owners, who were almost singlehandedly responsible for the design and execution around […]

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 […]

Some Church installations 2016:

We have been very busy over the last year, converting a number of church campuses over to Honeywell Evohome zoning, as well as in many cases updating the boiler plant at the same time. Evohome was originally designed for domestic use, allowing a room by room control of heating.  We’ve found that sophisticated commercial heating control systems are great if you employ a dedicated plant room manager – but for many light commercial applications, it is simply too complex for those expected to control it. There are huge energy savings to be made by only heating the areas in use at certain […]

Norwegian Chalet, imported by the Marquess of Tankerville

We work on some interesting houses in our job, and this was one of them.  Hidden away in a rural location near Tunbridge Wells, in around 1906 this house was erected in the grounds of Greystoke House, home of the Earl of Tankerville. The house had first caught the attention of the Marquess of Tankerville whilst on holiday in Norway, so, naturally, it was disassembled and brought over to Great Britain.  She planned to use it to board visiting guests at Greystoke. The Marquess died in 1922, having handed over the property to the China Inland Missionary Commission in 1918.  It […]

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 […]

Listed building with warm air heating, new iron rads and Evohome zoning

Our customer in South London owned a Grade II listed building.  It had been extended over the years but still retained many original features. Interestingly from a heating perspective, it had warm air on the ground floor, and no heating on the 1st and 2nd floors, just a couple of towel rails.  The warm air was provided by a downflow Lennox open flue unit, and the hot water and towel rails by an Ideal Classic wall hung boiler.   A domestic gas meter fed the building, so to limit costs and upheaval it was important that we ended up with […]

Listed Building in Kent gets a new boiler and 12 zone iPhone control

The brief was to replace an old Potterton boiler in the basement with a new unit, and make the system more efficient.  Spread over 3 floors and a cellar, this building is Grade 2 listed, and therefore represents a challenge when alterations to building services are required. We looked into replacing the boiler in the cellar with a modern condensing unit, and relining the chimney.  However, there were adjacent chimney pots that were in use, and also there were plans for the cellar which meant that our customer would prefer the boiler to be resited to an otherwise unused store […]

Listed building gets a new boiler and Evohome zoning

Our customer bought a fantastic building constructed in 1868, located in Carshalton, Surrey.  Listed inside and outside, it was built to the requirements of the author Mark Rutherford (real name William Hale White). It incorporates many interesting features, for instance the inside walls are three bricks thick, because Mr White required silence and solitude in his work. The chimneys were all internal to the building, to minimise heat loss.  A Victorian eco house, no less. We were asked to upgrade the existing installation of heating, which dated back to the 1980s.  Although the radiators and pipework were in reasonable condition, […]
