Hello! I’m wondering which will cost more - to run our heating system with an inefficient/broken expansion vessel for a minimum of six months from now, or to call out an engineer (£100 excess). Our house is a new build and still under warranty. I noticed the pressure in our unvented system dropped to zero within a day of being topped up. No obvious leaks, so it’s likely there is a hole in the expansion vessel membrane.
The plumber won’t come out to meet the terms of the warranty except in emergencies during the restrictions. He has suggested we just keep refilling the loop until the vessel is filled with water (which will seep through the hole in the membrane). This sounds to me like it will add up to a lot of fuel inefficiency over the next 6-18 months or however long the restrictions last. Sooo... would it be more cost effective to call another company out to replace it (ie not under the warranty) and instead pay the £100 cover excess? We have a cancer victim living here, so they ought to at least do that. Our gas bill is normally about £350 per year, if that helps with calcs.

Should add that’s about 6350kWh of gas per year when the system is working as it should.
