I have a 2100 sq ft hse, with a zoned oil heating sysstem (living area and bedroom area). I can do the following off of the oil heating
1) Water heating alone
2) Water plus Living are
3) Water plus bedroom area
4) Water plus bedroom plus living area
Last year I put in a backboiler as well as the oil. The problem I think your plumber is pointing to is getting a backboiler strong enough to run all your rads, whcih is the same problem I have. We went for a solid fuel stove instead of a backboiler, as we could get more power out of it. Still however, it is not enough to hear all zones of the house on its own, so we wither have it heating one zone only (bedroom or living area), or use the oil burner to boost it also.
My opinion is that it was well worth doing, our oil bills have fallen dramatically since. I would look at a stove, rather than a standard backboiler though, as you will get more out of it heatwise.

Wexfordman
There is no problem incorporating a solid fuel heating appliance into an existing oill fired heating system once it is installed properly with a unrestricted gravity circuit between the stove/boiler and the hot water storage cylinder. This circuit should be of 25mm diameter metal pipework. (no plastic/polyethylene pipe to be used)Is there major hassle involved in linking the stove in to an existing central heating system ? I like the idea of a stove but not the thought of having to dig up floors and /or have pipes running up the walls in to a hot press.
TRV's are mandatory if applying for seai grant, I feel the pain Shane too
Opps, didn't register 2006!
Another point is that I would certainly not like to use TRV's on a solid fuel systems. You could quite easily have a fire lit for the parish, close all TRV's, and system could potentially overheat!
You heard the latest, they seemingly now want 10sq earth to the pump!
Hi Villa1,
Duffman originally asked about zoning with back boiler. Heinbloed came in and recommended instead of zoning, to install TRV's. I would not recommend TRV's with solid fuel. I am not sure about what you mean "Are TRV's meant to be closed?". They should be open until the temperature surrounding them reaches the set temperature on the valve, then they will close.
For me, the question is when the DHW cylinder is heated to capacity, then all the TRV's close, the homeowner still has a fire lit for the parish, where will the heat disapate to? At least with no TRV's the room should be able to take more heat.
Who said anything about fitting trv's on solid fuel systems?.
Are trv's meant to be closed
I thought the original post was to do with connecting a solid fuel stove to an existing heating system.
If the system is designed and installed properly there will be no problem with overheating.
