What’s in the Itho Whole House Solution?

Our Whole House Solution comprises technologies at the cutting edge of energy efficiency in ventilation, heating and hot water and heat pumps.

Ventilation

Modern, energy efficient homes are more airtight than ever before. This means they need powerful, yet equally energy efficient ventilation to prevent a build up of moisture, odours, condensation and other conditions attractive to dust mites.

Itho’s continuous mechanical extract ventilation (MEV) systems are designed for exactly this purpose. With MEV, a single ventilation unit is installed in the loft or cupboard. The unit constantly extracts contaminated air from all wet rooms while fresh air enters the home through trickle vents. This creates a continuous flow of air through the home, keeping the environment, clean fresh and comfortable for (human) occupants.

Mechanical ventilation with heat recovery (MVHR) provides the same ventilation benefits as MEV while also heating the incoming air to the home. With MVHR, an air intake duct replaces trickle vents and a heat exchanger is installed in the loft. Both the incoming and outgoing air pass through the heat exchanger, with up to 91% of the heat from the extracted air transferring to the air about to enter the rooms of the dwelling.

For the ultimate in whole house ventilation, choose DemandFlow, Itho’s fully automated ventilation system. Using CO2 sensors in every room of a dwelling, DemandFlow adjusts fan power according the ventilation requirement, ensuring that air quality for occupants is always optimum without consuming any more energy than necessary.

Heating and hot water

Heating and hot water are huge factors in energy consumption - as well as major home comforts. This is why they are high priorities for our design engineers.

Harnessing the energy of the sun are the CombiSolar preheat systems, which offer huge reductions on the cost of heating water. CombiSolar combines a solar cylinder, a drain back unit, one or more solar collectors and – uniquely – a condensing combination boiler to provide on-demand hot water.

The Aqua Max Condensing Combination Boiler uses a stainless steel heat exchanger and advanced electronics to ensure that it always operates at the lowest possible power setting while providing an unlimited supply of instant hot water.

For instant boiling water in the kitchen, Itho has created the H2OTAP which can fit into any home, old or new. Requiring just a 5-litre boiler behind the kitchen plinth the H2OTAP can replace the kettle and provide instant boiling water for preparing hot drinks, disinfecting equipment and other kitchen applications. In a typical family home, The H2OTAP can reduce utility bills by up to £150 per year.

Even further savings can be achieved with Itho’s SHRU Shower Heat Recovery Units. SAP eligible, these waste water heat recovery systems (WWHRS) recover up to 60% of the heat from outgoing shower water and transfer it into the shower-bound supply. This means that taking a shower will cost less – or that occupants can shower for longer using the same amount of hot water.

Heat pumps

The Hybrid HP Cool Cube is compact, easy to install and highly efficient, providing more than enough heat for an airtight home – and up to 40% energy efficiency improvements over conventional condensing boilers. It works by warming internally extracted and outside air to 3kW with its heat pump, while the condensing boiler is on hand to provide a boost of an additional 24kW.

Itho’s ground source heat pumps can provide up to 80% of the heat needed in the modern home. They reach down as far as 150 metres, extract heat from the ground and increase its temperature before supplying it to an underfloor heating system by day, or to the hot water storage tank by night. In summer, the ground pumps can introduce coolness from the ground into the home.
