Currently I have a valiant ecotec heat only boiler and a vented system with rads upstairs and ufh down. I would like to remove the hot water tank from the bathroom to free up space and possibly fit ufh upstairs.
Is it possible to replace vented tank with an unvented horizontal tank in the loft maximising living space but can I keep the existing vailant heat only boiler?
Any advice suggestions, appreciated.
