With the introduction of the government’s Renewable Heat Incentive (RHI), there is an increasing interest in all the technologies associated with the scheme. This CPD gives an overview of a range of policy initiatives in Renewable Heat, an introduction to the different technologies and looks at some of the benefits and issues you need to consider when using renewable heat. This CPD seminar covers the following topics: Introduction to REHAU, DECC Heat Strategy & Renewable Heat Incentive (RHI), Ground Source Heat Pumps, Biomass Boilers (incl. district heating), Biogas/Anaerobic Digestion, Solar Thermal & Underground Thermal Energy Storage.

WHAT IS THE RENEWABLE HEAT INCENTIVE (RHI)?
INTRODUCTION
Government created incentives schemes to end users to increase uptake of renewable
technologies to meet EU legally binding 2020 carbon reduction targets.
2 types:
Feed in Tariffs (FiT) –
ELECTRICITY
Renewable Heat Incentive -

INCENTIVES FOR RENEWABLE HEAT
RENEWABLE HEAT INCENTIVE (RHI)
- RHI provides client an income for every kWh of
renewable heat produced.
- Only commercial buildings in Phase 1 - domestic
properties will be included in Phase 2 (Summer
2014)
- District heating eligible for Phase 1 (multiple
buildings) but only if heat generated from biomass
or biogas

10. ©
REHAU
RHI PHASE 1 – NON-DOMESTIC
KEY CRITERIA
- Payments are paid over 20 years to the client (quarterly payments)
- Tariffs are fixed once application is accredited
- Heat must be metered
- OFGEM administer the scheme
- Tariffs are index-linked to inflation

HEAT METERS
Heat meters are required for RHI compliance as
the payments are based on eligible heat used,
not heat generated.
MID Class 2 compliant is minimum standard.
2 types of systems:
- Complex (more than 1 meter)
- Simple (1 meter)
The system owner provides OFGEM with meter
readings on a quarterly basis.

PART L BUILDING REGULATIONS
RENEWABLE HEAT IS MENTIONED
“When replacing a heating appliance, consideration
should be given to connecting to any existing local heat
networks. If the work involves pipework changes,
consideration should be given to providing capped off
connections to facilitate subsequent connection to a
planned local heat network.”
L1B & L2B
“Providing appropriate facilities at the construction stage can make
subsequent enhancements much easier and cheaper, e.g.
providing capped off connections that can link into a planned
community heating scheme.”

RENEWABLE HEAT IS MENTIONED
If thermal energy is supplied from a district or
community heating or cooling system, emission
factors should be determined by considering the
particular details of the scheme.
Calculations should take account of the annual
average performance of the whole system (i.e. the
distribution circuits and all the heat generating plant,
including any Combined Heat and Power (CHP), and
any waste heat recovery or heat dumping).

GROUND-SOURCE PROBES
PE 100 PROBES & NEW GENERATION PE-RC
PE 100:
- Standard pipe material in UK market
- Should be manufactured to SKZ HR 3.26 test
regulations
- Lower pressure losses due to flow-enhancing
bend (coefficient of pressure loss  = 0,34 )
Point load standing times
comparison between PE 100 and
PE-RC
New generation is PE 100-

GROUND-SOURCE THERMAL PILES
EXPLOITING THE BUILDING‘S FOUNDATIONS
Pipework can be integrated into structural piles to
exploit ground-source energy.
PE-Xa is more suited to thermal piles due to its
improved bending radii (no joints needed in pile).
Thermal piles have to be used for heating and
cooling.
Helical pipes can be used to
reduce installation times and
increase heat transfer over
meander thermal piles.

GROUND-SOURCE LAYOUT
EXAMPLE LAYOUT & PIPEWORK REQUIRED
In most projects, multiple ground
loops are managed using an
external manifold.
This is typically housed in an
external chamber (either pre-fabricated
or built on site).
Benefits:
• Reduced condensation risk
• Ease of access
• Less pipes entering plant room

28. ©

GROUND-SOURCE ACCESSORIES
MANIFOLD & CHAMBERS
Modular manifolds:
- Offer flexibility on-site due to modular design
- Up to 12 ports per manifold
- Low pressure losses due to 2 ½ internal
diameter
Manifold chambers:
• Made of PE with an integrated polymer manifold
• Up to 20 port chambers possible
• Can be pre-assembled in factory or holes drilled
on site

INTRODUCTION
Typically use wood chip or wood pellets for heating.
Most systems installed today are heat only.
Biomass CHP (gasification / pyrolysis) coming to market

BIOMASS
BIOMASS DISTRICT HEATING
Biomass district heating schemes work well
because:
• Biomass boilers are often bulkier than traditional
boilers, hence typically located in external plant
room, not individual houses
• Require regular wood chip or pellet deliveries to
only one central plant
• Can be located discreetly on site extremes
• Qualifies for Renewable Heat Incentive

38. ©
REHAU
DISTRICT HEATING
DEFINITION
Hot water or steam is centrally produced
- Transported via an insulated pipe network
- Connected to individual properties via a heat
interface unit
- Heat metered
- Heat delivered via conventional heating systems

39. ©
REHAU
DISTRICT HEATING
BENEFITS
Large carbon savings possible
Economies of scale – increase efficiency
Ideal for technologies not feasible on individual
properties (e.g. biomass / energy from waste)
Future proof – easy to change fuel source
Minimise maintenance using one central plant –
no individual gas checks required

PIPE SIZING
IMPORTANCE OF OPTIMISING THE FLOW / RETURN TEMPERATURES
Most flow temperatures are ca. 80°C:
- Extends pipe lifespan
- Makes a safer network (no steam)
Ensure return temperature is as low as
possible (high ΔT):
- Reduces pipe size - > reduce capital
costs
- Reduces heat losses (improves
efficiency)

Fermentation of organic substances
occurs when:
