Back boiler and electric pump for an Aarrow Ecoburn 9

mark_j

Morning

We have had our Aarrow stove for over a year now and we are very very happy with it, we have it going most evenings,weekends and days when we are there together, and both being warm blooded out door folk we havnt had the need to have the gas central heating on yet this year, so our last 6 months gas bill has been peanuts.

When the log burner is going you can feel the difference in every room of the house but the last couple of weeks i have been looking into fitting a back boiler to it.

The back boiler is just over £200 to buy, but im sure my fabricator friend could make a better one for me if i took the stove to him for a quarter of the price.

Its more the electric pump to push the hot water around my radiators that im wondering about, im interested to know what make of pump people are using for their systems,how much current it is drawing and their thoughts on it and if they would do anything different

Im under no illusion that it is going to get each radiator to 25c and they will depending on how big the fire is get each radiator only mildly warm.

I know i will have to take the log burner out and then take up the carpet/floorboards in our living room to tap into the radiator pipework, drill holes through the fireplace to pass pipes etc, but i have a practically free supply of seasoned hardwood so if i can continue to keep away from buying alot of gas then i want to

What is peoples thoughts and experiences???

Thanks Mark

Apparently wood fired ch, especially stoves, are not the best. By taking the heat out you reduce the efficiency of the stove significantly and also have a greater risk of creosote.

In terms of pumps, I would have thought any standard ch pump would do. I would be more concerned about some form of safety pressure relief system if the ch pump fails, as the implications of the water boiling off at the back of the stove are pretty serious.

Either 2 pumps in series with some form of warning if one pump fails would do it, not sure how this is covered by existing systems. In this scenario in a gas boiler, the ch would turn off the gas supply. Bit mor difficult with a well stoked fire.

agree with other posters, make sure you have a high limit stat at least attached to the system, so it will kick in the water if the temperature gets too high and you havent got the pump going, you dont want the water boiling in the system.
