Combination boilers

Combination boilers do not use cylinders or water tanks. They give instant hot water and aren't based on stored hot water unlike other types of boilers. Since other types of boilers store the hot water in a cylinder for ulterior uses, and since the hot water is not used immediately, some heat is wasted and inefficiency is inevitable. That’s why combination (combi) boilers are in many cases the most efficient boilers. We offer a premium system that incorporates a Condensing Water Heater, Condensing Furnace, Condensing Boiler and Heat Recovery Ventilator, and which is already pre-wired for air conditioning. All of these functions are contained in one powerful system that requires less energy to operate than competing products.


Regular boilers

A typical regular boiler system – often named open vent boiler and heat only boiler - provides central heating and hot water incorporating a feed and expansion cistern, and also a hot water cylinder (often installed around or in the airing cupboard) and water tanks (usually located in the loft). This is the design of old conventional boilers, but it can also be used by new high-efficient condensing boilers.

Sealed boilers (System boilers)

System boilers also referred to as sealed system boilers, use hot water cylinders as regular boilers. But, unlike regular boilers, they do not need any water tank in the loft.

Programmable Thermostat - A programmable thermostat can save you money on your utility bill - up to 33%, if used as directed. You set up to adjust the temperature when you are away from home or asleep - when you don't necessarily need optimum comfort - and your HVAC equipment runs less. Plus, your heating or cooling comes back to a comfort level automatically when you come home or wake up. We offer a variety of heating, cooling, and humidity control products.

Indoor Air Quality - Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentrations of some pollutants.The “green design” movement in HVAC emphasizes maintaining adequate indoor air quality while reducing energy consumption. The use of air filters can trap air pollutants and reduce the amount of dust in HVAC systems. Dust can serve as food to grow mold on wet coils as well as ducts reducing system efficiency. Poorly maintained dehumidifiers and air conditioners can lead to high levels of pollen, dust mites, and fungi in a home. These biological irritants can cause eye, nose, and throat irritation, shortness of breath, dizziness, lethargy, fever, and digestive problems. Unvented kerosene and gas space heaters, leaking chimneys, leaking furnaces, back drafting from furnaces, gas water heaters woodstoves, fireplaces and gas stoves can all lead to high levels of carbon monoxide. High levels of carbon monoxide can lead to fatigue in healthy people and chest pains in people with heart disease. Higher levels of carbon monoxide can lead to impaired vision and coordination, headaches, dizziness, nausea. Carbon monoxide at very high concentrations is lethal. To prevent carbon monoxide poisoning one should have a trained professional inspect, clean, and tune-up central heating system (furnaces, flues, and chimneys) annually and repair any leaks.

Solar Solutions - By taking advantage of the Earths greates power source, the sun, you can reduce your carbon footprint and your electric bill. Solar Power is Clean, Renewable, and Abundant. By investing in solar energy for your home or business, you secure energy independence! The sunlight hitting your roof can provide enough energy for your hot water needs year-round. With a solar electric PV system from Lindstrom-Sprague Mechanical Services you can eliminate 24,084 lbs. of Co2 pollution in the first year. This is equivalent to reducing your auto driving by 28,901 miles or eliminating about 723 forty-mile commutes. We also offer smaller scale solar solutions including The SunSource Home Energy System by Lennox. This system is the one of the simplest ways to bring money-saving solar power into your home. This system can be used with as few as one or as many as fifteen solar modules per outdoor untit. This unit allows you to start small and expand over time to add more roof modules for even greater savings.
