Our Terms & Conditions

… to the Agreement between Sustainable Homes Scotland Ltd. trading as Paul Heat Recovery (The Company) and The Customer.

A) The Agreement

1. Agreement for Design Services only is executed when the design fee has been received in full to initiate the design.
2. No Agreement shall come into being between the Company and the Customer for supply and/or installation and/or commissioning until the deposit has been received in full.
3. On payment of the design fee and/or deposit, the Customer enters into the Agreement and its Terms & Conditions.  The agreement will consist of the most current quotation and/or design and/or estimate and these Conditions.
4. These Conditions do not limit or exclude the statutory rights of the Customer.
5. If at any time any part of these Conditions is held to be or becomes void or otherwise unenforceable under any applicable law, the validity of the remaining provisions of this Agreement shall not be in any way affected or impaired thereby.

B) Purpose of the system

1. The Heat Recovery Ventilation (MVHR) system is designed to provide sufficient ventilation, extract pollutants and surplus moisture under normal domestic circumstances and to effectively reduce the ventilation heat losses.
2. Unless otherwise stated, the system is not designed as a means of space heating. If a post heater is installed, the Company takes no responsibility that the space heating demand will be covered by the system. It is the responsibility of the Customer – who will need to gain specialist advice, e.g., from a Passive House Designer – to determine the heat load of the building and to ensure that the arrangements for space heating are sufficient.
3. The heat recovery system can distribute to a certain degree warmth from rooms with higher temperature levels to other rooms. It has to be noted, that there will be some temperature differentiation. If habitable rooms are not equipped with a central heating system, a thermal analysis is necessary to evaluate the temperature spread.
4. The Goods are supplied strictly on the terms that the Customer has satisfied itself of their suitability for its purpose.

C) Operation of the system

1. The system is operated on three levels: normal ventilation, reduced ventilation (when out of the house) and boost ventilation (short maximum ventilation for quicker extraction of humidity and smells).
2. MVHR system extracts used and polluted air on a gentle, but continuous level. It might occur that steam from shower or bathing is taking longer until it is extracted, compared to usual extractor fans.
3. The system is designed to operate at max. 30dB(A) in bedrooms and all habitable rooms (almost inaudible) and max. 35 dB(A) in extract rooms (in normal ventilation mode). In boost mode some noise will be audible.  Customer to advise the Company if special requirements for noise levels are required to allow alternative specification.
4. The electrical consumption of the system is based on an efficient ducting system and clean filters. The power consumption of a defroster and possible post heater are not included.
5. If no electrical defroster is installed, the system will operate on a frost protection mode, which will switch off the system if outside temperatures fall below a certain threshold (about minus 3 degrees Celsius).

D) System Configuration

1. No allowance has been made for overcoming any obstacles for the ducting, such as beams, joists or floors.
2. The specified door gaps to the finished floor level (usually 10 to 15mm) or door grilles need to be put in place for the correct operation of the system.
3. All supply and extract ducting should be located within the thermal envelope. If supply and extract need to run in unheated space, additional insulation (about 100mm) is necessary, which is not included in this quotation.
4. The HRV unit and defroster need to be easily accessible for filter changes and maintenance.
5. Ducting between the intake and exhaust and the HRV unit, which are located within the thermal envelope need to be insulated vapour resistant to avoid condensation.
6. The warranty of the system is conditional on the system being installed in accordance with the Domestic Ventilation Compliance Guide for England and Wales, and relevant statutory requirements, by competent persons. Damages and poor performance due to poor workmanship or deviation from the design are excluded from the warranty terms.
7. The design drawings require your written approval of the HRV unit position, duct sizing, system layout, valve and grille positioning prior to first delivery to site.
8. The Company needs to rely on the Customer to verify the positions and sizes where structural elements can be penetrated. It can therefore take no responsibility for the structural soundness of such penetrations.
9. As the Company is currently not in receipt of a fire strategy for this project, no fire dampers have been included in the quotation. These can be priced and supplied, on receipt of your requirements, if needed.
10. Where at any time after the signing of the agreement the Customer requests variation or modification in the design, specification, materials or drawings of the Goods, provided that the variations or modifications are accepted by the Company, the costs thereof shall be borne by the customer.

E) Design Services

1. Design is carried out to Passivhaus design guidelines and includes:

a)      Positioning of the MVHR unit to limit the length of cold duct runs within the thermal envelope and make optimal use of the building layout.

b)      Specification of cold duct insulation to avoid condensation and minimise heat losses.

c)       Duct layout to minimise the length of the ducting system, and its complexity, and to avoid warm ducts outside the thermal envelope.

d)      Specification of external grilles.

e)      Specification of the duct system to limit the air velocity of peripheral ductwork to below 2.5m/s.

f)        Best position of room valves (inlets and outlets) to optimise air circulation and avoid short-circuits.

g)      Specification of room valves to avoid noise and achieve optimal spread of air.

h)      Specification of silencers and cross-talk attenuation.

2. Design is based on the following constraints as standard:

a)      All supply & extract ducts to be located inside the thermal envelope

b)      No more than 2 penetrations of the air tightness layer

c)       No PVC flat channel ducting

3. Customer to advise the Company of any requirements that differ from the above design constraints or any other special requirements.

4. The scope of the design does not include: Fire dampers, volume flow dampers, filter elements, condensation traps and controls.

5. Design duration is generally between three and five weeks.

6. Online MVHR Design Information Checklist is available to support the initiation of the design: www.paulheatrecovery.co.uk/services/ckecklist-0/

7. Design can commence once the floor layouts are frozen and the location of the MVHR unit has been agreed.

8. The Design Service includes five iterations following confirmation of frozen floor layouts and an agreed unit location.

9. The Company reserves the right to charge additional design fees should the floor layouts and/or location of the MVHR unit change significantly.

10. In the event of cancellation of the design, outside the cooling off period of 7 days, the Company shall be entitled to recover all reasonable costs which it has incurred, or for which it will incur liability, before refund of the design fee.

F) Installation

Should installation be included in the Agreement, the following applies:

1. The Company aims to provide best service at competitive installation prices. Therefore, confirmation is required that the site is ready for the first or the second fix to avoid unnecessary site visits.
