34.4kW Riva Compact Combi Boiler High Efficiency Condensing (HE)

Any
hot water system must be able to meet the requirements of the whole house. That
is all sanitary units and whatever appliances are connected e.g. dishwashers,
washing machines etc. Bathing tends to create the largest demand for hot water;
each bath will require approximately 65 litres of hot water. The size of the
property and layout of the rooms that have sanitary fittings also needs
consideration. Long pipe runs supplying hot water would probably be
un-acceptable for centralized instantaneous heater systems, and a combination of
systems may be more appropriate.
Should I replace my existing heating system?
This can be a difficult question. If you heat with electric resistance heat, rising electricity prices may force you to switch to a gas, oil, or heat pump system that is more affordable. If you currently have a gas- or oil-fired furnace or boiler, the decision to replace it depends on its age, condition, and performance.
If your furnace or boiler is old, worn out, inefficient, or significantly oversized, the simplest solution is to replace it with a modern high-efficiency model. Old coal burners that were switched over to oil or gas are prime candidates for replacement, as are gas furnaces with pilot lights and without an induced draft fan.
