Thinking of Having a Stove Fitted?

Thinking of having a Stove Fitted?

I see thousands of stoves so see all sorts of different installations. I also come across lots of problems with stoves that are badly installed or don’t work very well.

Buying a stove is something you will probably only do once and I am very happy to chat to anyone in this position and give lots of advice.

What stove?

Buy a well-known make of stove so that spare parts will never be an issue.

Buy from a reputable dealer so there is a guarantee.

Avoid unknown internet sellers selling cheap unknown stoves. I have seen stoves bought off the internet that have parts missing or made of a strange size so are hard to adapt to British Standard flues. Then, in future, when new parts like fire bricks or fire bars are needed, there can be a big problem sourcing replacement parts.

Cast iron or steel? This comes down to personal preference but as long as either are good quality and well-built they will last a long time. Cast iron takes longer to warm up but then retains it heat over a longer period. I have a steel stove and love it.

The Installation

Use a HETAS registered installer. HETAS installers are highly trained and experienced and will know all the regulations. On completion of the installation the HETAS installer will sign off the job. If the installer is not HETAS registered then you will need to get Building Control in to sign off the job and this is an extra cost.

Thinking of installing in a single storey extension with a new twin wall flue up the outside of the house? Beware, as many of these installations suffer terribly from blow back where smoke and fumes come back into the room.

There are reasons for this.

The first is that the twin wall flue up the outside of the house is a metal tube out in the cold and a cold flue will not draw.

The second reason is that the flue may simply not be high enough to get up into the clean airflow. Look at an existing chimney up on the highest part of the roof. The chimney stack and pot are there to get the top of the pot up in the clean air flow with no eddies and currents that will cause a disruption to the natural draw. Now look at where the new flue may terminate. Will it get a clean air flow?

A third reason is that a high chimney means there is a greater pressure difference between the top and bottom of the flue. The greater the pressure difference then the greater the draw in the flue.

As you can see, there is an awful lot to think about.

Do I install stoves? No, I only sweep.

All joints should be airtight. Here we can see a large gap between the flue pipe and register plate. The stove was re-installed.
