Heat Recycling – On Site Renewable Heat – Seasonal Heat Storage

Heat Energy Recycling is performed by Interseasonal Heat Transfer. IHT is a new form of on site renewable energy that channels naturally occurring heat from the sun down to the ground in summer and back to buildings in winter to heat buildings without burning fossil fuels. Interseasonal Heat Transfer integrates solar thermal collection in summer with heat storage in ThermalBanks to double the efficiency and Coefficient of Performance of ground source heat pumps in winter.

Interseasonal Heat Transfer captures surplus heat from summer sunshine, stores it in ThermalBanks™ in the ground and releases it to heat buildings in winter.

Interseasonal Heat Transfer also captures cold on winter nights, stores this in ThermalBanks™ in the ground and releases it to cool buildings in summer.

Solar Radiation vs Heat Demand

Solar radiation does not match Seasonal heat demand
Interseasonal Heat Transfer recycles summer sunshine to provide heating in winter

An IHT system includes an Asphalt Solar Collector, a ThermalBank to store heat energy, and an ICAX Skid which incorporates a heat pump and an ICAX Black Box electronic control system.

IHT™ can save over 70% of carbon emissions compared to using a gas boiler for heating.

IHT™ can save over 80% of carbon emissions compared to using standard air conditioning and chillers for cooling.

IHT™ can save over 100% of the annual cost of running your heating system if you are entitled to claim the Renewable Heat Incentive.

Planning and Energy Recycling

The Merton Rule requires new developments to demonstrate at least 10% of on site renewable energy before planning permission is granted. Interseasonal Heat Transfer can now be used to generate over 40% of on site renewable energy and make large savings in annual running costs of both heating and cooling.

Alternative Energy – Seasonal Heat Transfer

At last there is an alternative to the standard renewable energy options that have been available for some years. Seasonal Heat Storage integrates the strengths of solar thermal collection in summer with seasonal thermal storage in ThermalBanks – in order to deliver heat through heat pumps more efficiently in winter.

Low Carbon Economy benefits from Energy Recycling

Nearly half the energy consumed in the UK is used in buildings – mostly for heating, cooling, lighting. Interseasonal Heat Transfer is able to offer a significant reduction in consumption of fossil fuels for heating and cooling in the move to a low carbon economy – by saving surplus energy in summer and recycling it in winter.

Sustainable Heating Systems powered by recycling solar energy

ICAX delivers Sustainable Heating Systems powered by solar energy. ICAX ensures that the systems delivered are in balance over the year as a whole by using detailed thermal modelling to balance the heating loads of a building with the cooling loads. Where the heating load is larger than the cooling load ICAX uses asphalt solar collectors to collect heat in summer in advance of the heating season. Where the cooling loads are larger than the heating loads ICAX uses an asphalt heat rejector to dissipate the excess heat and balance the system.

IHT is a dynamic system that adapts to the changing temperature loads as the building use changes, weather patterns change or global warming shifts the balance of requirement for the building.

Ground Source Heating and Cooling – GSHC

ICAX uses an integrated combination of solar collection, seasonal thermal storage and ground source heating and cooling to provide Interseasonal Heat Transfer – economic renewable energy.
