Hi - I have a gravity heating system with storage tank + smaller expansion tank in the loft. In an airing cupboard I have a VERY old cylinder and heating control unit. The hot water has recently stopped and on investigation it seems the flow of water to the cylinder is blocked. In addition the immersion unit has corroded and has blown.
The old immersion unit is too difficult to remove without cracking the cylinder and thus I have been advised to change the cylinder, water flow pump and piping and thermostat unit. I have requested a budget-wise solution and need an idea of what I could expect to pay - rough estimate. Any advice/estimated figures would be appreciated :?:
