Hello,
I'm planning to get a new Vaillant ecoTEC to replace my old Ravenheat 820/20 which finally gave up on life. I'm struggling to choose between the ecoTEc pro 24, pro 28, plus 824 and plus 831.
The house is a very small back to back end terrace with 3 bedrooms and 1 bathroom across 4 floors. 7 rads in total - 2 in the basement, 1 single and 1 double on ground floor, 2 on first floor and 1 on second floor. The old Ravenheat was about good enough since I can put up with not using the kitchen hot tap whilst someone else showers but a little more power might be nice. The bath is very rarely used since I'm too tall!
The plus 831 seems like overkill. The pro 24 and plus 824 work out about the same price if I take into account the 2 years extra warranty on the plus versus 2 years extra insurance on the pro. The pro 28 would give a little extra power.
I've three questions:
1. Any strong opinions on which boiler best suits my needs?
2. I currently have 15mm pipework on the hot water 22mm pipework on the CH to the Ravenheat - do these match the specs for the ecoTECs?
3. I saw a video online suggesting the internal filling loop on the plus is perhaps more of a disadvantage than an external loop for the pro if repairs are ever needed down the line. Is this worth taking into consideration?
Many thanks in advance if you have any comments.
