Remove Ideal iStor boiler and fit super new Viessmann and Fabdec system

We’ve published a similar story here before, which is one of the reasons why our customer in this case study called us. He recently bought a relatively new property (2011) with an Ideal iStor on the second floor, it wasn’t working properly, and he had been advised that it had been a money pit since virtually day one. The other reason he got in contact with Hot Water & Central Heating Ltd was that he had used us for boiler installation before, in this case around 11 years ago (not in this house!). A refreshing number of our early customers […]
Viessmann light commercial in Edenbridge

Pyser Optics are a long established company in Edenbridge, specialising in equipment for broadcasting and defence markets across the World. In fact, in a previous job, I used to order Broadcast TV camera lenses from them! Small world, they say. We were asked to specify a replacement for a 96Kw output SIME cast iron sectional boiler, which had been classed as unsafe. It was used to heat the main administration block of Pyser. Our heat calculations suggested that an 80Kw boiler would be more than adequate. We provided Pyser Optics Ltd with two options; a cheaper solution using a mainstream […]
Ideal Istor finally gets the heave ho

Our customers in today’s case study bought a ‘new build’ around 8 years ago, in the Redhill area of Surrey. Inside, these properties are very spacious, and the rear elevations have got multiple Velux windows, L shaped lounges, very light and open. Unfortunately, the developers chose to ruin their good work by fitting an Ideal iStor boiler. Our customer had fortunately taken out a British Gas Homecare contract on theirs, but after years of visits including a protracted one from the manufacturer themselves, and having replaced every part, some more than once, plus a powerflush etc, they decided it was […]
Worcester-Bosch 1 Keston 0

For this case study, we find ourselves in Oxted, Surrey. We like Oxted, because it is a lovely, virtually unspoilt town (if you exclude Morrisons) full of coffee shops and yummy mummies. I suppose it is similar to Sevenoaks with all the good bits squeezed into a smaller area. It is also very close to Hot Water & Central Heating Ltd HQ, so we get a lot of projects there. A larger house, this had a Keston C55 boiler and a significant number of radiators. The Keston boiler had been unreliable (no surprises there) so we suggested a Worcester-Bosch alternative. […]

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 […]
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 […]
Complex house heating system of the future (in 1998) gets updated
For this case study, we are in Ealing, West London. Our customer rang us to say he had inadvertently bought a large house with a woefully complex heating system around 8 years ago. The first time he viewed the house, it was perfect – but they never went into the garage. On the second visit, he popped his head into the garage area, and found it completely full of commercial plant, and a ambient temperature of over 30C. Since then, many a central heating specialist has escaped having seen the garage; apparently they are brimming with confidence until the door […]
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 […]
