Vented system, what's the best Feed and Expansion tanks; also would combi work fine in a big house.
Anonymous user 23/02/2024 - 2.54 PM
Got a 4 year old vented heating system, looking to replace F/E tanks in loft. Plastic ones (Polytank) looks quite thin and flimsy. Any better alternatives? metal? In case the tank breaks, any way to act as precaution (thinking of a overflow tray underneath)... would Combi work fine in a 4 bedroom + 2 loft rooms, 1 shower, 1 bath house, enough power and pressure to reach everything? for example a 37kws combi.
Are you a tradesperson and able to answer this question?

The plastic feed and expansion tank wont break because is made for the purpose but must be placed on good flat hard surface.
The combi boiler can work. I recommend vaillant eco tech plus 937 which fitted with 20 litre storage heated ready for use, but as well you need to have good main water pressure and flow rate at least 18 l / min of 3 bars.
