I want to phase the upgrading of my heating system in a 3 bed semi.
First I want to have installed a new combi to heat a small underfloor heating system, and 3 radiators, and our tap hot water.
At a later date (2 – 5 years) I may want to purchase a wood burning stove with a back boiler, and have connected into the heating system, via a storage tank. I may want solar panels also to feed in. Is there a combi that is compatible for both scenarios? most wood back boiler needs a vented system(although there are some stoves that are pressurized) , and the combi is pressurized. I don’t want to have to buy and install the storage tank at the beginning, as this will be done in phase 2, for financial reasons.
Summary; I want to future proof my heating system, with combi gas now and wood and solar with tank later. Can wood boiler and solar, with tank, be retrofitted into a combi system???
jgglastonbury, Since the combi will direct feed hot water, it may give issues linking with solar and woodburners. Have a look at accumulator tanks, this may be ideal for longer terms plans but you may have to drop the combi. end
