Within a few days of the RHI launch, Icenta has already received a number of enquiries for heat meters and heat energy calculators which can be used as part of the scheme. One option, the ICT Heat Meter, is an all-in-one in-line compact heat meter that measures the energy used to heat water in kw/hr. It is economical solution for flow rates up to 2.5m3/hr with a choice of a pulsed output in kw/hr or an Mbus output. For larger flow rates, Icenta can offer multi jet or Woltmann hot water meters (or a cold meter for chilled water applications) in conjunction with a wall mounted heat energy calculator. Also, 2 temperature pockets must be used, one for flow and the other for return.
