Depends whether economy or ecology is paramount. I'll address from economics/technology.

The problem with wood (and we have burned a lot over decades) is that it is in inconsistent in combustion properties; its combustion can only be controlled via regulating the air supply, tends to massively deposit tars in chimneys, requires very careful seasoning, is labour intensive, and has at best about half the calorific value of coal or oil.

Both coal and wood give relatively poor response to changes in heating load - a bad characteristic, especially for cooking combined with central heating. Note that Agas avoid this by being a massive heat store and restricting water heating to dHW only (no ch)

Over time the price of all fuels tend to equate, but if you have your own wood supply then this would be a significant factor- assuming you don't own an oil well or coal mine. Otherwise, oil is the cleanest, needs no labour, and gives a fast response.

There is a respected green man locally who distributes solar panels and is critical of much of the sales hype. I am an engineer myself and I find him technically sound. He is quite catagorical "there is no financial case for solar panels. You install them for ecological reasons, not to save money"

For many years I ran a small oil boiler in tandem with a wood-fired ch boiler. The trick is to use motorise valves linked to a water thermostat (a cheap one that clips onto the 'flow' pipe is fine), so that the oil boiler cuts-in when the ch water temp drops eg at the early morning switch on or when the fire is out!. This would be a relatively cheap option too, and lessens dependence.

Off-peak electricity heating your hot water cylinder, or even a thermal store heatinfg tank, may be worth examining. You could also consider one of the heat-pump options - but that is a vast topic in itself.

Rayburn supreme has a rating of 35000 Bthu/hr.
355 is mechanically identical, but Rayburn cheat and by opening it up and feeding twice as fast you can achieve 55000 but not according to the BS.
Most people find it hard to keep the Supreme going on wood and impossible to bank overnight.
Linking to an oil boiler is successfull and the simplest way is to use a Neutraliser . Forget motorised valves.
The boiler stat can be set to a lowish level so that it will go off when a set circuit temp is achieved and trip in again when the temperature is Flagging.
