- Reducing energy demand is always the best starting point. There are any factors that may affect your energy needs, such as the number of occupants in the house, their ages, how warm it needs to be, whether it is occupied all day and so on. Your overall strategy should start with trying to minimize the overall strategy should start with trying to minimize the overall energy requirement. All the basic rules of energy conservation should be observed and there is plenty of advice about this available. Insulation is nearly always the prime option, even if it is very expensive. It should last indefinitely and should not require any attention. But there is sometimes a limit to levels of insulation that can be achieved, e.g. losing wall space due to internal insulation might be unwelcome and external insulation might be impractical.
The following list suggests some initial questions to consider:
- Will a heat pump be suitable for my house and lifestyle?
- What different heat pump options do I have?
- What will a system cost to install?
- What are likely long-term running costs?
- How disruptive will the installation be?
- What CO savings will I achieve?
- What else could I do instead?
