Hot water from a condensing combo gas heater would certainly be cheaper, but I don't have central heating! For some years now the owner of the building that I live in has the policy of installing a combo heater with central heating in apartments that become vacant. As it happens a few weeks ago such a system was installed in the apartment just under mine. I have seen it and I must say that I was not happy to see all those steel pipes running everywhere: over the ceilings, along the walls. And the heater itself was installed in the kitchen, taking up valuable space in that already tiny area. My new neighbours said that they intend to use the pipes as rails for mounting spotlights!
