The house didn’t have a boiler (only an old immersion tank) and it used ancient storage heaters. This meant the shower was cold, there was only ever five minutes hot water and it was impossible to heat the house with any flexibility.
We dismantled the storage heaters (which were full of tonnes of heavy bricks) and installed a new 7 radiator central heating system, replacing the immersion tank with a combi-boiler which left space in the boiler cupboard to fit a new washing machine (living without a washing machine is a nightmare).
We took the opportunity to fix up some other plumbing issues like re-routing any visible pipes so that they are hidden and we replaced the dangerous old lead gas pipe with a new copper one. We also installed a cooker gas point and a towel rail in the bathroom.
