Long term strategic role for heat pumps

• The 4th carbon budget ascribes a prominent long-term role for heat

pumps in achieving binding domestic emissions reductions

“The Government is committed to expanding the Renewable Heat Incentive to the residential sector and delivering a long term scheme to this effect”

DECC 4th Carbon Budget Progress Report, Oct 2012

“The Government has also consulted on Renewable Heat Incentive tariffs for domestic buildings, with a commitment that this will support all eligible installations since July 2009. The Government expects to publish details of tariff levels and eligibility this summer” DECC “The Future of Heating, Meeting the Challenge” March 2013

Domestic Air Source Heat Pump Market – Summary by Sector

New build 6000 6000 6000 6000 4kW, 6kW

Social Hsg 2900 6100 10000 15000 6kW, 8kW

Private Domestic retro 3100 4900 9000 13000 8kW, 12kW, 16kW

Total 12000 17000 25000 34000

New build: Requirement mainly for smaller units (4/6kW) due to low heating loads in new properties. Market growth limited due to slow housing market, unhelpful SAP treatment of heat pumps and builders seeking lower cost solutions

Social housing: Requirement mainly for small and medium size units (6/8kW). Will be a key sector for volume installations, RHI driving uptake in off gas areas

Private sector retro-fit: Requirement mainly for larger units (12/16kW). Oil boiler replacement becomes mainstream as oil prices increase and RHI helps cover marginal costs

Introducing Dimplex Smartrad

20


Co-efficient of Performance

• CoP affected by:

• Heat source temperature

• Heating water temperature (flow/return temperatures)

• Additional supplementary heating

• CoP continually varies

• A spot measure of performance at optimal conditions

• Much like car mpg figures

21


Space and Water Heating

• Heat pumps can provide both space heating and domestic hot water

– 35-55ºC water temperature

Radiators

• Sub-optimal flow temperatures required, i.e. 55ºC or above

• Compromises heat pump efficiency

– SAP correction factor

• Need to be oversized for use with heat pumps

22


Space and Water Heating

Underfloor heating

• Underfloor heating is traditionally considered to compliment heat pumps well

– Lower temperatures required

– Larger surface area, typically 35 – 40ºC

– Helps heat pump run more efficiently

• SAP benefit

– Screed can act as thermal store

• Not always cost effective or practical

• Slow to respond due to high thermal mass

23


Radiators that work with heat pumps

• Wall mounted, intelligently controlled, fan convector

heaters • Easily and cost effectively installed in new or existing

buildings

• Designed for low water flow temperature

• Optimises heat pump CoP

• Reduces heat pump running costs and CO2 emissions

• Ultra low water content

• Low thermal mass means fast response

• Controllable

• Individual room time / temperature control

• Space saving

• > 3 x output per metre of length than conventional radiator

• Does not require over sizing

24


Smartrad Range

• Range of 4 outputs: • SRX080: 0.8kW

• SRX120: 1.2kW

• SRX140: 1.4kW

• SRX180: 1.8kW

• Rated at 45 C flow temp,

fan speed 2

• Technical manual gives full

output range at varying flow

temperatures

• Choice of White Metal,

White Glass or Black Glass

Heat Emitter Guide for Domestic Heat Pumps

• Guide produced by industry

trade associations and DECC

• Aims to help appropriate emitter

selection for heat pumps

• EST field trial highlighted

appropriate emitter selection and

flow temperatures as a major

issue

• Uses a Star Rating to indicate

efficiency, encouraging lower

flow temps

• Highlights fan assisted radiators

as a particularly effective and

flexible solution

Solar Termal

Solar Thermal Systems

General Overview

• Solar Thermal uses renewable energy from the

sun to produce heat

• Solar panels produce energy from daylight

• Not specifically direct sunlight

• Means hot water can be produced even in cloudy

weather

• The most common applications are:

• Domestic hot water

• Swimming pool heating

The basics

Solar Thermal Systems

General Overview

1. Solar Thermal collector absorbs solar irradiation and converts into heat energy

2. Heat energy is removed by a heat transfer fluid (water/antifreeze)

3. Heat transfer fluid circulated by a small pump

4. Heat energy stored in a domestic hot water cylinder

5. A back up heat source is required for days when light levels are limited

• Boiler, electric immersion, heat pump

Technology – Flat Plate Collectors

• The most widely used collector type in Europe

• Over 90% market share

• Ideal for domestic hot water heating or swimming pools

• Can be mounted on roof or integrated into roof covering

• May also be mounted on flat roofs

• Portrait of Landscape orientation

• Multiple panels can be connected together in series
