Start with demand
Describe the number of people at home, busy periods and whether demand changes during the week. Mention if the old system regularly runs out or if the fault appeared suddenly.
Understand the site
The available services, location and installation requirements narrow the options. Provide accessible photographs and plans for building work. Do not remove equipment covers or access a roof for an enquiry.
Compare suitable options
Ask for the exact model, installed scope, maintenance requirements and warranty terms. For running-cost comparisons, make sure the usage and energy-price assumptions match.
Keep the decision practical
A product catalogue does not confirm installation suitability. Ask for a written explanation of the recommended choice and any alternatives worth considering.
