Greenstar 8000 LPG 70Kw Boiler Cascade in listed building

Our customer bought a large house near Ashford Kent, in a rural setting. They knew the property needed a lot of work, the previous owner had dedicated his life to refurbishing it, and to be frank, there was an awful lot still to be done when he handed over the keys. This was a refreshing refurbishment to be asked to get involved with; our customer had read this blog from time to time, and we were on his list for this project before we knew about it. Unlike some customers, who would buy a large property, have it completely remodelled […]

Archie Kidd boiler replaced (*) with another oil boiler pioneer

Our customer lives in Kent in a 1890s set of railway construction workers cottages. When the property was refurbished in 2004, he specified an Archie Kidd (Thermal) VHE Model 1 oil boiler. This was before the UK Government had latched onto condensing boilers being the future. In fact Archie Kidd had designed his Model 2 prototype in 1959 as part of his strive for energy to be conserved and not wasted needlessly. The Kidd Model 1 should last in excess of 30 years, so it was a shame to remove this now discontinued British leader in the history of heating […]

Navien Oil Boiler Cascade replaces Biomass plant

For this case study, we are on a 660 acre farm on the Surrey/Kent borders, comprising a number of industrial units, home and other uses, where once 6000 pigs used to roam. The owners of the farm complex were influential with some of the first biomass developments, and while advising other users over 20 years ago, they fitted a plant in their farm industrial area. Their Farm2000 biomass plant used timber and other waste, and was connected to a large underground steel pipework distribution system. Heat on the lucky units and houses connected to the system was unmetered, and it […]

Kensington large house boiler renewal in lockdown

This installation started as a phone enquiry relating to a house in the Kensington area of London in early 2021. The story, relayed by owner’s son in law, was that his parents had a light commercial boiler that had failed some months earlier, and they had found it difficult locating a contractor prepared to consider utilising the existing chimney for a new boiler. As we are based in Kent, Kensington is a bit of a schlep to drive for a quotation. We have done a fair bit of work in Kensington during 2020, much of it that would make really […]

Nursing Home fast track boiler plant cascade renewal during COVID lockdown

Our case study today refers to a job we carried out in the first lockdown in 2020. A local care home had earlier used our services to repair a Worcester boiler in a wing of their building. We got a call during the first COVID lockdown, when everyone was at home and the roads were deserted. Their main boiler plant was giving problems and they wanted us to look at it. The main boiler room looked quite ordered from the outside; two flues sticking out had cages and it looked purpose made. however once the door was opened things didn’t […]

Viessmann Cascade in large house

For our case study today, we were called to inspect a large house in Surrey, completely refurbished around 7 years ago, with multiple underfloor and radiator heating zones. The house had a basement boiler room, containing a pair of 46Kw Vaillant EcoTec 46Kw light commercial boilers, using a cascaded flue system and a header. A maintenance company had paid a number of visits to keep the boilers running, but they were plagued with frequent reliability problems. The last inspection had also raised issues with the flue header and chimney lining installation, even though they had been maintaining it for years […]

New warm air unit replaces Johnson & Starley Economaire

Today we are in the Crystal Palace region of South London. Our customer has a J&S Economaire 50 warm air unit. Over the last few years the unit has become somewhat unreliable and needed resetting frequently. Her warm air maintenance company had made some ultimately unsuccessful efforts to improve it, so it was time to replace. We recommended a MultiCalor Udara 15Kw downflow unit, this is from a manufacturer we are familiar with, having fitted many of their MC range air handling units over the last 10 years. The Udara range was launched three years ago and features a wide […]

Game changing oil boiler installation in Leatherhead, Surrey, 10 year warranty.

Oil boilers are considered to be rather outdated now, what with the UK Government pledging* to have us all driving around in electric cars and heating our homes with hydrogen. While not saying where the electricity, or the hydrogen, will be coming from, of course. *Sensibly, these promises are being made with a timescale of at least 15 years away, meaning they are worthless. Amidst these pontifications, a boiler manufacturer has quietly beavered away and come up with a very low Nox (Nitrous Oxide) oil boiler; in fact, it is billed as the least polluting oil boiler you can install […]

Johnson & Starley warm air replaced by Worcester Bosch boiler and EasyControl

This case study begins in a terraced house in Tunbridge Wells, Kent. A kitchen renewal has a short while ago necessitated the warm air heater being relocated into the garage. Our customer had some concerns over the way this part of the work had been carried out, and it turned out they were right to be worried. Generally speaking, moving a warm air unit is not easy… there’s ductwork deep under the floors, which are usually concrete, and most older warm air units have a vertical ‘open’ flue, akin to a fireplace. So moving the box itself isn’t difficult, it […]

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 […]
