Craftsman and Tudor houses in Queen Anne and Ballard were finished with plaster and thin walls. Heat is baseboard, a wall unit, or a leftover oil furnace. A heat pump warms those rooms and dries them in the same run.
Ask for a heat pump sized to keep your home warm on the coldest usual winter day. The price uses the WA and utility programs your address qualifies for. No sales call, no information sold, no pressure.
