My Boiler is around 10 years old, it's a Vaillant Turbomax Pro 837e, it's not a condensing Boiler. It was bought with a focus on DHW performance and, regrettably, no real consideration was made towards running costs.
Today, 10 years later, I'm seeing monthly gas bills of £120-130/month over the Winter months, which I think is excessive. We cook entirely with Electric, the Gas is just for Heating and Hot Water.
The Bungalow isn't perfect, it could do with a bit more insulation, some of the Windows are now 10 years old (possibly need reglazing) and I do have a big Patio Door in the Kitchen (albeit very modern and with the highest efficiency glass I could buy), but even with those things in mind, I think it's still overly thirsty.
Furthermore, I don't think the performance is that great. Whether or not a problem has developed I don't know. I'm about to have a heating engineer out to look at it, once I can find one I feel that I can trust not to come and simply tell me I need to replace it.
I have the Hot Water control turned almost all the way up (58° on the display) and the Radiator dial also very high. Yet, the water seems to cycle between hot and luke warm. The heating also seems to struggle, it takes something like 2.5 hours to raise the temperature of the house from 19° to 21°, is this normal? It seems disproportionate with the amount of 'fuel' it's using.
Question is, is there much in the way of 'setup' and 'tuning' on these things? Could it simply be 'out of adjustment'? Or do they not work like that?
