    Cascading Vaillant boilers with weather compensation

    That is the alternative (I think). Only real reason for two is redundancy. I did have another theory that two boilers were cheaper to run that one. The reason being upstairs has always been warmer than downstairs (fewer rooms, hot air rises etc). But if upstairs called for heat and...

    Cascading Vaillant boilers with weather compensation

    Hi After talking to Vaillant's tech desk today, I am even more confused about their setups. Basically I need 2 x Ecotech Plus 630 system boilers cascaded and I would like them both with weather compensation controls. I understand that it's not possible to have 2 x VRC 470f controllers...

    Stuck diverter valve + programmer - 90 mins labour??

    Hi I rent out a flat in Reading and the tenant recently had a problem where the CH would not come on, but the HW (combi boiler) was fine. Initially the agent said it was the pump which didn't make much sense to me - so I queried whether the programmer was set correctly and if the valve was...

    Storm Heating broke my boiler

    Update...after a worryingly large number of phonecalls to Homeserve, Vaillant sent out their own engineer to look at the boiler. He immediately diagnosed the problem - Storm Heating had removed a part to fit the washer, incorrectly fitted the washer, failed to solve the leak and then fitted the...

    Can you hire power flushing equipment

    http://www.hss.com/g/51610/Central-Heating-Flusher.html But from some of the disclaimers I've seen, I guess there are risks attached depending on why you need the power flushing in the first place (sounds like it treats the symptoms, but doesn't solve the problem if you have corrosion/sludge).

    Storm Heating broke my boiler

    I have spent a large amount of money on independent plumbers/boiler engineers over the last 5 years or so to fix various problems with our central heating system. Unfortuantely, I've had my bad luck finding good quality tradesman - some of who have exacerbated relatively minor issues into much...

    Storm Heating broke my boiler

    we have a pretty large system - 2 x Vaillant VC GB 242 boilers, a 300l megaflo and around 60 rads - I think when it does come to replacing them, it won't be a cheap job.

    Storm Heating broke my boiler

    Unfortunately I've had a complete nightmare with them and Homeserve (I know I am going to get criticised for using boiler insurance companies here). Basically, one of our vaillant boilers (15 yrs old or so) developed a small leak. I called Homeserve who sent out Storm Heating. The engineer...

    Timer for a 4.8kw element in water cyclinder

    Thanks crafty1289 We had an electrician who put in some outdoor lights linked up to a Wylex distribution board. He did a really neat job wiring everything up for us. I'll give him a call tomorrow to see if he can do something in the interim. Out of interest, how come there are no timers...

    Timer for a 4.8kw element in water cyclinder

    It's an Everhot water cyclinder (400 litres) for domestic use. Something made the system unhappy (kept on blowing fuses) which caused me to investigate the problem (and I'm sure someone is going to tell me how on earth did our electrician install something like this). The setup is this...

    Timer for a 4.8kw element in water cyclinder

    Hi I've searched through the forum. Unfortunately, I can't find any topics relating to timeswitches for water cyclinders with an element above 3.2 kw. The booster element (3.2 kw) is on a fused switch as it is rarely used. The problem is 4.8 kw main element (the existing timer has...

    Timer for a 4.8kw element in water cyclinder

    Hi I'm looking for a replacement timer for our water cylinder (bottom element is 4.8kw and the booster element is 3.6 kw) but most of the timers I've found are for loads up to 3.6kw. I need one to turn on/off during the Economy 7 period for the bottom element (booster is on a switch). Any...

    Sizing of new boilers

    @ htgeng - I think this is a lesson for anyone that has a plumber/boiler person out to fix a boiler that he/she is not familiar with. We got to the stage with him that he had bought all 3 PCBs for the boiler, at just over £100 each, and he wanted to replace them all. I finally called it quits...

    Sizing of new boilers

    When we had the boilers installed just over 10 years ago, they appeared to be the best available on the market. Vaillant have told me that they were a 'new generation' of boiler, but obviously Vaillant have improved the reliability, efficiency and performance of their newer boilers. The...

    Sizing of new boilers

    Thanks for your response ChrisR. We have had problems with one of the Vaillant boilers for some time now. Basically, the flame reset switch on the front of the boiler would continually pop out (varying from every few hours to every few days) causing the boiler to shut down. As both of the...

    Sizing of new boilers

    I'm in the process of looking at replacing two existing Vaillant VC GB 242 EH system boilers (around 10 yrs old). I'm currently looking at the Vaillant or Worcester Bosch range. I want to re-calculate the required boiler size in the house (I have the individual room measurements) in order that...

    Central heating water/domestic water mixed

    Onetap - Thanks for your response. Excuse my ignorance, but why should the central heating system not be filled up with softened water? The house I live in is circa 10 years old. It was setup so all the water was softened, except the drinking cold water taps in the kitchen.

    Central heating water/domestic water mixed

    I have had a bit of a nightmare with plumbers recently. I guess it's like all professions, sometimes it can be hard to get the right guy for the right job. This morning I called a plumber, recommended to me by a couple of friends. I said to him that I thought the central heating/domestic...

    Central heating water/domestic water mixed

    Any ideas how long I should run for? We have four bathrooms upstairs/one toilet downstairs/three kitchen and utility sinks downstairs (the two kitchen cold water taps run directly off the water mains as the rest of the water goes through a Waterside water softener before being distributed...

    Central heating water/domestic water mixed

    Hi We've got a DIY man in at the moment who's fitting a new bathroom and he has unfortuantely caused a problem with our central heating/domestic water. Basically our system is slightly complicated (because of the size of our house). We have two Vaillant VC GB 242 EH system boilers, both...
