Hi All,

Just stumbled across this site and read some really useful threads.

I am in the middle of considering which type of boiler to choose for our 4 bed bungalow.

Existing System - Ideal Elan, cylinder in loft only used for DHW. Heating is via Economy 7...not good !!

At our previous property we comissioned British Gas to install a Worcester 28CDi Combi, which we were very happy with, although the drop in hot water flow rate did take some getting used to! As I need to fit this system myself, I believe that a Combi is the best choice due to my limited knowledge of heating systems, although a Mechanical Engineer by trade.

The flow rate has been a major decision in my replacement boiler choice and at first I was considering a boiler with an internal store to get around the long delay in hot water reaching the tap and an increased flow rate.

After careful consideration I was opting for the Baxi Combi Maxflow WM which has a 54lt store and can deliver 16lt/min until the store has depleted. However, I guess this flowrate then drops whilst the store is replenished and I have been unable to locate the flowrate.

Further investigation revealed that the high end Condensing Boilers are offering 16lt/min delivery all the time (at the standard 35 degree temp rise) and in particular the Baxi 133HE Plus Condensing Combi Boiler looks a good choice and will give me a far more efficient system.

I guess this choice will not solve the initial delay in receiving hot water?

Some of the threads have indicated that there is specialist equipment required for fitting condensing boilers, is this true?

Any help would be greatly appreciated in helping me choose the correct system.

Regards

Andy

I have a Vaillant Turbomax, which is not suitable for your purposes since it
doesn't go as high as 16ltr/min ( at least, I'm not sure, there is a more
powerful model than the one I have, which is a 28kW ), however they do have
a feature called Warmstart, which, when enabled, keeps a couple of litres of
water warm in the boiler loop so that in effect instantaneous hot water can
be had ( neglecting the time it takes to get through the HW pipes of
course ).
