They also generate less CO2, there are no transmission loses and the
thermal efficiency is higher.


CCGT is pretty effcient, you still have transmission loses though. Is
a condensing combi running in condensing mode when only heating HW?

Its only the tax on others that makes solar panels viable.


What "tax on others" for Solar Thermal? Only stand alone HW only
systems or hybrid systems where the other heat source is a biomass
boiler are eligable. "Biomass boiler" does not include a log burning
stove with boiler.

Solar Thermal that is part of a hybrid system with an oil boiler are
*not* eligable for RHI payments. Mains gas rules you out of RHI right
at the beginging.

RHI comes from central government not from a levy on everyones
electricty bill like the FIT payments.

How much wood have you burnt in the last week? Using lots to get the RHI
payment up?


AIUI Harry has a log burning stove, not sure if it also has a boiler.
Not that it matters log burners aren't eligable for RHI payments.


I have a log burning stove, no RHI payments.
The fuel is free.
Some, I grow my own by coppicing.
The rest I gather oportunistically.
I have a saw in the back of the car.
It's a rural area, so lots of windfall timber.
I am also in a canal society, we cut down lots of trees as part of opening
up a derelict canal.
I have an estimated five year supply stashed away.

In very cold weather I run the stove for a couple of hours in the evening,
warms the whole house.
Approx 1m3 of wood does me for a heating season. Less if it's mild.
