Heat Pumps Today

SUMMARY RESULTS FROM HEAT WAYV HOME HEATING TCO ANALYSIS: Note on gas boiler phase out Gas boilers will be phased out sequentially in the UK starting with a ban on installation in new homes from 2025, progressing to a ban on replacements in 2030 and a planned elimination of all gas boilers by 2038. The EU and other countries that have a substantial installed base of gas boilers are also in the process of their elimination. Addendum: Notes on Home Heating TCO Calculations 1. For consistency in deployable technology, the analysis is based on 12,800kWh as the medium energy usage for a medium sized household. 2. Throughout the analysis, energy consumption per annum is shown by tari using Peak, O-peak and Blended rates. The O-peak tari isn’t available to all proposed technologies today, but it is highly likely to be available in the future. The Blended tari is being proposed by the large REP’s for space and hot water heating only and would be the O-peak tari plus 3 hours during the Peak tari. 3. Not all of the proposed technologies would benefit from having access to O-peak taris because of their method of operation, for example: a. The Heat Pump needs to operate for up to 12 hours to generate sucient heat and hot water, it is not an “on- demand” system, and consequently would likely be running through the day when the Peak taris are in operation. Additionally, this system will require a secondary immersion type hot water booster. b. The Electric Panel System is primarily space heating technology and is more frequently operated during Peak tari hours. Additionally, this system has a secondary immersion type hot water heater to complete the demand cycle. c. The Hydrogen Boiler is shown for comparison purposes. Domestic hydrogen is not readily available for purchase and the practicality of deploying these boilers in a UK consumer wide gas-grid network has been deemed as impractical and unfeasible. 4. The Heat Wayv One, space and hot water heater has a 40L hot water tank and a recycling space heating system. The system is an all-in-one appliances and would be able to take advantage of the O-peak tari. 5. No electrical based technology is comparable to a gas boiler on cost alone, given that all the current green initiatives are levied on electricity generation. However, if the blended taris were levelled then electric powered appliances win hands-down on zero CO 2 and lethal CO emissions alone.
