Products designed for the installer, by an installer, that protects the environment and preserves its future
There has been a lot of talk about the new The Clean Air Act introduced last year by Michael Gove, resulting in existing and potential customers wondering if stoves are going to be banned. To clarify, stoves will NOT be banned although stoves, fuels and the installation will need to be much more energy efficient.
From 2022 all new eco-stoves sold must be more efficient and cleaner burning to meet the new criterior. This means that when installing all new stoves, which will be 80%+ more efficient by 2022, more focus must be on installation to ensure minimum heat loss. Current installation techniques leak large amounts of heat above the sealing plate and through the brickwork. In most cases sealing plates are only 1.5mm thick steel so very little heat is retained. Using The Stove Box eliminates all these problems, pushing heat back into the room, keeping hotter for longer, making your stove even more effective. It will also ensure your stove installation is compliant.
Back in 2014 we carried out a test using a register plate install and the same test using The Stove Box. A 5Kw multi fuel stove from town & Country was used in Kiwa testing laboratory, Cheltenham. A better insulated surround would expect to result in higher temperatures on the inside of the surround and clearly reduced temperatures on the outside. This was indeed found to be the case with The Stove Box installation, giving significantly higher and lower average temperatures respectively, as illustrated below for the final test. The stove in the The Stove Box gets hotter quicker with temperature differences of about 10°C in the first few burning cycles and settles at about 5-6°C higher after sustained refuelling cycles.
When a stove is chopped into an existing chimney breast, (this could be on an outside wall, not in a warm laboratory) using a register plate system, heat from the stove will escape into the atmosphere, not in the room. Most installers chop out an opening, buy a blank plate, cut out a neat hole for the stove pipe to fit through, seal with silicon which creates a hot spot in the breast above the plate. The Stove Box has a larger hole in the top to allow a separate adjustable collar, which has a heat gasket protecting, reducing heat transfer, creating a quicker, and safer installation. The collar is then bolted into position with sealing rope around the stove pipe, stabilising the stove and pipe. We also have a registered design on our register plates which are also adjustable.
Heat transfer also can be a problem when a false chimney breast is built. It creates a chamber to fit a stove in, in a no chimney situation, creating all sorts of heat problems. When we carried out another heat loss test, a thermocouple was placed above the register plate (approx 75mm) showing 56°C and the stove pipe was 200°C. Using The Stove Box in this situation confines the heat in the chamber, projecting more heat forward into the room not in the breast.
A recent example of why you should use The Stove Box installation, was a client who had recently built a false chimney breast using blockwork and plaster. After 10 days the plaster had cracked due to heat loss through the blockwork and breast. This would not have happened if they had used The Stove Box, as explained previously, it confines the heat. Our new Chimney Breast Kit includes The Stove Box as part of the package.
The Stove Box has changed stove fitting throughout the UK due to its environmental benefits. It is approved by building control and HETAS. Kiwa, a UKAS-accredited company, carry out testing (and often certification) on appliances, construction materials, electrical and water products. They also carry out energy monitoring field trials to carbon verification. The overall effect of the findings described will result in a householder feeling more comfortable and hotter (both quicker and ultimately) in a room with a Stove box installation than one from the same appliance burning under the same conditions in a conventional register plate installation.

The Stove Box cannot be fitted without a fire resistant interior included. We have a number of adaptors for connecting the flue liner, patented adjustable collars which bolt on allowing a sliding movement for easy access to above the box for connecting to the liner and for servicing.
