Hi everyone. We’re replacing a leaking flat roof on a small extension and need to decide between a lean to or gable end roof. Cost is mostly the deciding factor, is there a clear winner? Any other things to consider with this that i may not have thought of? thanks.

Thanks Phil. I keep reading different quotes so I need to get some of my own really. Max budget is really what will make the most economical sense, difficult for me to give a max as I’m really not sure on costs. This property is 1950s semi. 9 rooms in total. Does every room need a unit or does the blowing air heat up other rooms? Any advice appreciated.

cheers guys, I’m evaluating all my options and what would make the most sense. I intend to get quotes for air to water as well as air to air and then make a decision. I think if I were to go air to air I’d just have a normal vented direct hot water cylinder. Cheap to install but expensive to run, however with electric showers I shouldn’t need a particularly big cylinder. I have looked at cylinders with inbuilt ashp, but they aren’t cheap. Does my approach make sense? It’s all a bit new to me. My original intention was just to install oil, but I don’t think that would be logical now.

Thanks for your reply. You say it makes expensive hot water-are heat pump hot water tanks expensive to run? My choice is between this or immersion really. I’m avoiding installing oil or lpg, and for ashp I’d rather air to air over air to water.

Hi all, I’m in the process of renovating a property which currently uses an old gravity fed hot water cylinder with immersion heater. The heating is old electric storage heaters. The village has no mains gas, so after much research I have decided on using an air to air heat pump for the heating. For the hot water i am looking into an air source hot water tank, and i came across the AquaThermica by Tesy. Does anyone have any input as to the quality and efficiency of this tank? Or if there is a better make on the market? Im particularly interested in how loud it is as if its vey loud it may need moving from the airing cupboard in my current plan. Thanks
