What size of boiler do I need?

To maximise efficiency, boiler selection should be based on an in depth survey of the property and an estimated calculation of heat loss inside the dwelling. Once the energy (kW or BTU/hr) requirement for the property has been assessed the boiler should be matched against this energy rating.

If I have a Rinnai external water heater mounted outside my house, wont it freeze in winter?

No. All Rinnai Water Heaters will protect themselves down as low as -15°C providing the electrical supply is left ON. They will NOT however protect any external pipe work against frost damage.

What is °C delta T or °C ΔT?

They both mean the same. It is the amount of temperature rise required to get the incoming water to the required outgoing temperature. Here we use an average incoming temperature of 10°C so if you required an outgoing of 60°C it would be classed as 50°C ΔT.

Where can I fit a Rinnai External Water Heater?

Basically anywhere, outside the building. If the position of the heaters complies with the positioning of a concentric boiler terminal as per BS5440 then it is fine.

If I fit a Rinnai External Water Heater do I have to protect it against frost?

No all Rinnai Water Heaters will protect themselves down as low as -15°C providing the electrical supply is left ON. They will NOT however protect any external pipe work against frost damage this you have to take care of. If you fit an external pipe cover box this will assist in the insulation of the pipes.

Does solar heating only work when the sun is shining?

Solar heating technology works on solar radiation, not just sunshine therefore solar heating can be effective on overcast days.

How does solar energy provide water heating?

Solar radiation is used to heat fluid in solar energy collectors (best on south facing surfaces). Typically fluid is pumped through a hot water storage cylinder, In that cylinder heat is exchanged between the collector fluid and your domestic hot water. Innovative systems incorporate high efficiency condensing water heaters to maximize solar gain refer to solar boosted.

Does a solar hot water system replace a hot water system?

No the solar heating works alongside the heating system to reduce the reliance on fossil fuels. The heat system is still needed to complete the system.

Will the solar collectors freeze during winter?

No - Many solar panels are filled with a suitable heat absorbing liquid (glycol) this doesn't freeze in cold conditions.
