The 5800i AW is the air source heat pump with an extremely low global warming potential. The SAP assessment examples below highlight the carbon emission savings that can be achieved by upgrading an existing home heating system to a new Bosch air source heat pump.

House Type assessed: Semi Detached 2 story home, 6 rooms in total with cavity wall insulation and loft insulation. SAP software is approved by the Government approved contractor, the Building Research Establishment.

Smart heating

The 5800i AW has the very latest intelligent and innovative technology at its core, including natural refrigerant R290 (propane). Using ambient air as the main regenerative energy source, the 5800i AW pulls in heat from outside, transfers it into hot primary water and circulates it through the house. This generates all of a of a home’s heating and hot water energy requirements. Now that’s smart heating.

With a SCOP (Seasonal Coefficient Of Performance, indicating energy efficiency) of up to 5.5 and an A+++ ErP rating, the Compress 7800i LWM is highly efficient in its category.

Using the solar energy stored in rock, soil, lakes or groundwater (i.e. warmed by the sun), the ground source heat pump draws out natural warmth to heat and cool your home – with a very low CO₂-equivalent 4,802 tCO2eq. CO₂ equivalents (CO₂e) are a unit of measurement for standardising the climate impact of the different greenhouse gases.

The Bosch Easy app is free to download and gives you energy monitoring of your boiler at a glance. (Wi-Fi and smartphone required)

Features like ‘Away’ mode, help you save energy when you leave the house. All it takes is one click to reduce your heating or hot water setpoint. Then, when you get home, you can return to the previous level of comfort in a click.

Just one feature among many, making it easier to be more responsible.

Quite simply, hybrids are a combination of an electric heat pump and a gas or oil boiler for heat generation.

The heat pump generates heat for 70-80% of the time* and, during colder months, the boiler acts as a top-up – only operating when it’s needed – giving all year-round comfort.

This process can contribute significantly to CO2 savings, and is ideally suited to decarbonising older or smaller buildings where locating the equipment is difficult.

The SAP assessment examples below highlight the carbon emission savings that can be achieved by upgrading from a G rated non-condensing boiler to A rated condensing boiler.

Hydrogen-blend ready feature

The hydrogen-blend ready boiler featured is ready to run on a blend of up to 20% hydrogen and gas.

The UK government is exploring hydrogen boilers as part of the solution for decarbonising home heating.

They are currently consulting on two things:

• The decision to mandate hydrogen ready boilers in the UK (decision expected in the short term - 12 months/2024)
• The role of hydrogen gas in heating (2026). The first stage of the introduction of hydrogen into heating could be through blending hydrogen with natural gas.

So if the government does decide to go ahead with hydrogen blending, our boiler would continue working with no modifications achieving 6 to 7% Greenhouse Gas (GHG) savings using a blend of up to 20% hydrogen compared to 100% natural gas.
