    Can the Horstmann Electrisaver be wired up to my CH system?

    Thanks for the reply. You mention compatibilty problems, why would it not work with a new boiler but it would with an older one? Sorry to ask but I don't want to buy one if it is not going to work. Also as mentioned earlier we use the CH system to dry clothes on rads and with young babies...

    Can the Horstmann Electrisaver be wired up to my CH system?

    Hello again Dan I actually want the Electrisaver in the new setup to maximise future savings. We are planning to stay here for 5-8 years so along the way this little box could really pay for itself and some! How would it be wired up? Of course I will ask the gas fitter to do it...

    Can the Horstmann Electrisaver be wired up to my CH system?

    Hi Dan and cheers for the reply I think it would work well in our house for a couple of reasons. 1. We use our rads to dry clothes and a quick blast is all we need. Unfortunately we can't be trusted to remember to turn CH off so this could save money. 2. We don't use the timer much as...

    Can the Horstmann Electrisaver be wired up to my CH system?

    Hi Can anyone please tell me if the Horstmann Electrisaver can be connected up to my CH system? Basically the Electrisaver (http://www.horstmann.co.uk/water-heating.php) is a simple push button electronic timer that saves energy by remembering to switch off when you forget. It is marketed...

    Frictional losses in a Combi and the effect on HW flowrate?

    Hi I would like some help please choosing between 2 boilers, Baxi Neta-Tec 28 HE and the 33 HE. Max flowrate is 13.5 LPM for the 33 and 11.5 LPM for the 28. The difference between the two models is only £70 but I will only spend it if I will actually achieve the flow at the showerhead...

    Seeking Specs (KW and LPM) of Glow-worm Swiftflow 80 Combi

    Thanks for that. In that case I will probably get the "Glow-Worm Betacom 28A HE" which is £551 inc VAT on boilers2go. The specs for this combi say 24.5 KW max and 11.2 LPM so it should "at least" match my current 9 LPM for HW. That said, I wonder what a 12.3 LPM shower would feed...

    How do I calculate annual cost savings for replacement combi

    Sorry, I should have clarified that. Until very recently (start of cold snap), 17degc on the dial is basically off for the CH! I think maybe once or twice it came on at 4am. Also we have a very young baby and the Wife is paranoid the nursery will freeze unless we do it this way (ie CH on...

    How do I calculate annual cost savings for replacement combi

    Thanks for the replies guys. Some of you are saying that savings are possible by upgrading the "controls". Please can someone explain this to me as I would also like to do this. Does controls refer to the "timer"? A this moment I have a Honeywell timer hardwired to the boiler and also hard...
