Hi Hi gas_man_gaz, Your profile says that you are in SHEFIELD. Are you Gas-Safe / Corgi registered and if so, would you be interested in quoting for a boiler replacement? Current boiler is a condensing Ideal Minimiser FF80. Mains water, gas & electricity all easily to hand. Boiler is in...

Any idea on the questions posted above? Is it likely to be gas build-up due to corrosion or is it still air in the system? Would more inhibitor help of do I need to flush the system first? Dave

Thank you both for your swift replies. John, would you mind telling me what conventional heat-only boiler you chose? I'm looking at Worcester Bosch Greenstar - they have a s/steel heat exchanger and, if fitted by a recognised WB Engineer, a 5-year guarantee. Also in the frame are...

Hello again folks! Man I'll be glad when this boiler saga is all sorted, but I digress... Ever since BG replaced the heat exchanger on 6th Jan (now 15 days ago), we have had constant cut-outs of the boiler due to the activation of the dry-heat stat in the Ideal Minimiser FF80 boiler...

Thank you once again John and Tony for your replies. If it helps any, the combi boiler would NOT need to supply any showers (they are instant electric 8.4kW type) only the HW for washing, shaving and bathing. Even the waching machine (or dishwasher when used) are cold-fill machines. It...

Thank you John. Your reply kind of agrees with what these friends were saying... Looking at your figures a 100L bath will take 5 mins to fill at 20L/min Typical combi figures are 10L/min (?) meaning 10 mins to run and this figure will be affected (severely ?) if someone runs a hot tap...

Hi again folks. Need some advice as I thought I had settled on a boiler (a WB Combi), but now a couple of spanners have been thrown into the works, so to speak. Two of my wife's friends have just been to visit and both of them, separately I might add, have told us that combi boilers are...

Hi Tony If it helps the mains water flow rate is between 16 & 20 litres per min and the gas supply was judged to be OK - he looked at them both. Dave

Thanks onetap So, to make sure that I've got this straight: My current (25-year-old) copper HW storage tank is vented 'cos it has a cold water feed tank in the loft? I could get rid of this tank IF I change the HW storage tank to an UNVENTED type? If I keep the vented HW storage...

Thanks for the swift reply. Wife is interested in a combi boiler but isn't too keen to lose the DHW cylinder. Question is, could we retain the unvented (ie original) HW cylinder with a combi boiler (I think the answer is NO)? Could we have an unvented hot water cylinder in place of the...

Are the rads that remain hot upstairs by any chance? If the upstairs rads get hot whilst the downstairs rads stay cold, it is because hot water is less dense than cold water and rises - however, if the c/heating is OFF then no rads should warm up! If some rads get hot when the boiler is...

Hi folks Further down the path of having our c/htg boiler replaced. Latest thought is for a combi boiler - which can get rid of the F & E tank and the CW feed tank in the loft (something that I would like to do). Also with a combi the HW tank can be removed from the airing cupboard...

Thanks for that explanation - my knowledge is increasing slowly! Can this be added to ANY boiler? It seems that it would make the system more efficient - so instead of residual heat "leaking" into the basement from the boiler, it would actually do some good in heating the house? There are...

Thanks Jason Just to get this straight in my own mind so that I can ask the right questions when someone quotes... You are saying that the Baxi Solo is an OK boiler but doesn't need a pump overrun because it has an allow heat exchanger? But, it seems that you are also saying that the...

Hi, A further thought occurs. Would wiring the pump so that it continues to run to remove residual heat from the boiler's heat exchanger also necessitate a small change to the pipework - a bypass if some type? Research suggests it would. Would this bypass require a piped connection...

Thanks for the reply twgas. Are you saying that all that I would seem to need (given that you can't have a look at the system) is a wire that connects the bolier to the pump? I would expect the pump to keep running whenever the room stat & timer are calling for heat. As it stands, three...

As it says in the thread title really. What are these boilers like in terms of reliability? BG have just quoted for a Baxi Solo 24 HE to replace our problematic Ideal Minimiser boiler. So, is this a good boiler, average boiler or poor boiler? What about ease of fitting? The BG rep...

Hi guys, From reading the forum, I was surprised when I saw a 37 pcb. Was expecting a '41. No idea what has been fitted though as I was at work when the engineer came. Dave

Thanks Temprise, agile & nickso Boiler seems to be running sweetly at the moment, but I'll keep an eye out for flue seal problems. Thanks. PCB 37 has obvious corrosion around some resistors & diode between relay RL2 and capacitor C14 (see photos). Impressed by the BG engineer...

Hi again Tony It turns out that not only was a replacement thermostat needed but the water leak from the broken heat exchanger has also corroded connections on the pcb (a No. 37). Thermostat & pcb now replaced & system now working properly :) It has taken 5 engineer visits over the last...
