best system for solid fuel???

[CXR100]

whats the best way to do a central heating & how tater with solid fuel? seen some systems with 2 pipe stats on the flow and return from the solid fuel burner to switch central heating pump on/off. any ideas??

the two stats are to stop thermal shock to the stove which can cause corrosion to the heat exchanger and overheating. low limit stat to basically stop cold water from the heating system getting pumped into a hot heat exchanger by waiting for the primary gravity return to be warm enough so when the pump kicks in it mixes with the gravity return to keep the temp up. the hi limit stat to kick the heating in to take away excess heat.

thermal stores are great for solid fuel systems.

work their best when with a buffer/accumulator so it stores the heat created for when it is needed, need a fair sized room for a buffer though as they start at a minimum of 500 litres plus you'd still need a DHW cylinder.

Plenty of ways of doing it well, although if it's a completely new install and a blank piece of paper, I'd swing towards a decent Thermal store as a good starting point...
Have a chat with a local HETAS wet installer near you for advice (search the HETAS website for your local guys) and they will help you out...

In fact you don't need a separate hot water cylinder because most good heat stores incorporate hot water coils too.
One of the examples - Linszter LMT 2000 1V + DN20 Thermal store

yes you can use a thermal store but i personally dont lke them as you dont actually have much of a store of DHW.
