Hello all. ..first post so please forgive the lack of technical knowledge.
I'm looking at replacing an old potterton 100e regular boiler connected to a unvented traditional system.
Can't decide between the above high powered combi or going unvented with a ecotec 637 system boiler and 210 glendhill cylinder.
It seems most heating engineers prefer the unvented but I'm not sure it's a great fit for our place.
20 litres per min mains flow
Engineer said that there was 3 bar with the outside and kitchen tap running.
We have a large 15 rad house but well insulated. Current 100e which is 100000btu/ 30kw does the rads fine so I'm concerned that the 37kw system boiler may be overkill.
2 bathroom house and will want to run a decent shower in both.
However, at the moment there is only 2 of us living here. It is rare that both of us use the existing electric showers daily due to showering at the gym etc.
I guess I'm wondering if it's a waste of time heating and storing the water when it won't even be used daily, let alone 2 showers at the same time.
Also, if my incoming is 20 lpm am I really going to get the full benefit of an unvented system when the 843 combi can do 17.8 lpm anyway!
Anyone got any experience of the new ecotec 843?
Oh. .and 3600 for the combi. ..4320 for the system (both with vsmart)
Any views greatly appreciated
