I've recently discovered that you can retro-fit a wee back boiler to a Morso Squirrel and it would give enough for a couple of people having a shower in the morning. We have 2 squirrels - one in the dining room and one in the living room - does anyone know: a) how easy are they to fit retrospectively and b) can you have 2 running, one for showers, one for kitchen usage for example and c) are they any good at all or would I be wasting £240 (thereby) for each one?
Thanks for reading.
