How much heat do you need? We've renovated a row house in the Netherlands - very similar climate - with solid foam insulation and triple glazing. Haven't gotten to installing a heating system yet. Even in the current cold period it's perfectly fine indoors with a cheap hoodie on. If I didn't know it would make the place unsaleable, I'd be tempted to move forward without any room heating system at all, only a small on-demand water heater.

The estimates in that terraced house's energy performance certificate [1] are 15,992 kWh per year for heating, 2,324 kWh per year for hot water.

Of course these figures depend on how much of the day the house is occupied, how high the thermostat is set, and how cold the weather is.
