Ventilation Systems for Residential and Commercial Properties
J.R. Waddell and Sons Ltd are experienced installers of comprehensive ventilation solutions, offering systems designed for all property types. Our expertise covers a wide spectrum of technologies, from powerful, high-performance fans ideal for tackling moisture in specific rooms, to sophisticated whole-house systems that provide continuous, filtered air. We have the knowledge and equipment to create a healthier atmosphere in any home, whether it’s a modern new-build or a classic period property.
Our Ventilation Services in Detail
Heat Recovery Ventilation (HRV) Systems
Heat Recovery Ventilation (HRV), also known as MVHR, is the ultimate solution for combining energy efficiency with superior air quality. These systems work by extracting stale air while supplying fresh, filtered air, all while recovering valuable heat that would otherwise be lost.
Centralised HRV Systems
This is a whole-house system where a central unit continuously extracts stale air from wet rooms (kitchens, bathrooms) and supplies fresh, filtered air to living areas (bedrooms, lounges). Before the stale air is exhausted, it passes through a heat exchanger, which transfers its warmth to the incoming fresh air.
Centralised HRV Systems are best for new builds and properties undergoing major renovation where ductwork can be easily installed.
Key Benefits:
- Maximum Energy Savings: By recovering and reusing heat, your heating system works less, slashing your energy bills.
- Whole-Home Air Quality: A continuous supply of filtered air reduces dust, pollen, and pollutants across the entire property.
- Complete Condensation Control: Prevents condensation, dampness, and mould growth throughout your home.
Decentralised Single-Room HRV
What if you want the benefits of heat recovery in a single problem room, or in a property where installing ductwork isn’t feasible? A single-room HRV unit is the perfect answer.
We install the latest state-of-the-art, through-the-wall heat recovery ventilators. These units use a sophisticated ceramic core to recover heat on a “push-pull” cycle. It extracts stale air, ‘stores’ the heat, and then uses it to warm the fresh, incoming air.
Decentralised HRV Systems are best for existing homes, single-room extensions, or solving ventilation issues in specific areas without major disruption.
Key Benefits:
- No Ducts Needed: The perfect heat recovery solution for existing homes and retrofits.
- Targeted Ventilation: Solves damp, condensation, or stuffiness in a specific room (e.g., a steamy bathroom or a stuffy bedroom).
- Exceptional Efficiency: Recovers a huge percentage of heat, offering fantastic energy savings for that room.
- Whisper-Quiet & Smart: Operates almost silently and can use sensors to automatically manage air quality.
Mechanical Extract Ventilation (MEV)
Mechanical Extract Ventilation (MEV) is a highly effective and cost-efficient method for ventilating your entire home. A central unit continuously extracts air from all wet rooms, depressurising the home and drawing fresh air in through purpose-built vents.
Mechanical Extract Ventilation Systems are best for new builds or major renovations looking for an efficient, whole-house ventilation solution without the heat recovery component.
Key Benefits:
- Whole-Home Solution: Provides continuous, quiet, and low-level ventilation for the entire property.
- Cost-Effective: A more affordable whole-house system that meets building regulations for new properties.
- Eliminates Moisture: Excellent at controlling humidity levels to prevent condensation and mould.
Intermittent Extract Fans (IEFs)
Intermittent Extract Fans are the traditional, localised fans installed in wet rooms. They operate only when needed—for example, when you turn on the light or when a sensor detects high humidity—to powerfully extract moisture and odours directly at the source.
Intermittent Extract Fans are are best for upgrading ventilation in older properties, individual room renovations, or as a simple solution for dealing with moisture in specific problem areas.
Key Benefits:
- Targeted & Powerful Extraction: Quickly removes steam and moisture from specific areas.
- Simple & Affordable: Straightforward to install and operate with a low upfront cost.
- Flexible Control: Can be operated manually or automatically with timers and humidity sensors.
