Rinnai panels for Peckforton Castle

  • 26 Jul 2018

Rinnai has recently carried out an installation at Peckforton Castle in Cheshire, replacing its old direct fired stored hot water system.

Two HDC 1500i units from the UK’s leading manufacturer of continuous flow hot water heating units and systems were linked to solar panels as the main hot water heating source by contractor A P Mitchell.

Peckforton Castle, built in 1842 and completed in 1851, is a Victorian country house built in the style of a medieval castle and is recorded in the National Heritage List for England as a Grade I listed building.

In 2006, the historic building was repurposed as a popular luxury hotel and spa.


Adam Mitchell, for A P Mitchell, commented: “The brief from the client was to create a more efficient system, and at the same time to enact a reduction in stored water volume to give substantial saving in gas fuel consumption.

“But the new system had to still meet peak demand in the hotel, spa and event facilities.

“Our company provides a professional and comprehensive M&E building service, design, supply and installation; offering quality construction workmanship and value for money services.

“We pride ourselves on our quality of building services, workmanship excellence and client service.”

Rinnai’s HDC1500i is an award-winning range of continuous flow water heating units. The range was developed to guarantee the maximum amount of affordable, ecologically friendly, safe-temperature controlled hot water, on demand at any time, by even the busiest commercial user.

The Rinnai 1500i is engineered to the highest standard and is technologically advanced, with a plethora of features giving extra value.

A huge bonus onsite has been the savings on fuel over other forms of water heating solutions, which has been achieved by the added advantage that Rinnai systems will only raise the temperature of the water if required and that these smart condensing water heaters will only increase the temperature by the precise amount needed.

This ensures any solar gains are maximised and ‘boosted’ by a secondary heat source, thus ensuring the optimisation of both technologies.

A Rinnai unit used as a gas booster for solar systems will not only maximise solar gain, it will only use the correct amount of energy for the demand at the time and the rest of the time the unit remains inactive.

It is this, the booster, that ensures never-ending hot water, no matter the demand or conditions. Fossil fuel is only used when the renewable thermal energy store is below its set-point, thus reducing the dependency on fossil fuel and reducing CO2 emissions.

The Rinnai system produces usable hot water on demand, at the turn of a tap or the push of a shower button. The relatively compact footprint of the units also means they can be housed in tight spaces and still be easily accessible for maintenance and servicing.
