Englert Building Integrated Solar Thermal, PV and Rainwater Harvesting

The folks at Englert have a novel system that integrates a solar thermal system with their standing seam metal roofs (up to 35 year warranty), and offers a PV option. Produce your solar heated water for heating (hydronic) and domestic hot water, produce grid tied power, and harvest rain water for toilet, laundry and irrigation. Check out their system at Englert Environmental.

What we do on the roof is important because what happens below the roof is critical. More than a decade ago, we began imagining the roofing systems architects, builders and homeowners could use to face their most common environmental challenges.

Imagine a roofing system that protects your home or building, keeping it cool in summer, warm in winter and providing all the hot water and electricity you require.

Now envision a roofing system that captures 95 percent of its rainwater runoff, channels it through a debris-proof gutter system and deposits it in a rainwater harvesting tank for immediate use.

Today Englert Environmental is a leading provider of renewable energy solutions where metal roofing and gutters systems play a critical role in collecting solar energy and harvesting rainwater.

Partnering with key technology and service providers, including the foremost photovoltaic, inverter and mounting solution providers and the nation’s principal source of commercial and residential rain water harvesting systems, Englert provides world leading, best-of-breed technology, products and services.

What’s Wrong with Air Conditioning (and Heat Pumps)

Let’s look at the typical Central Air Conditioner. You have an air handler and heat exchanger indoors, and a condenser sitting outside. Your house is hot, and you want to cool it down. The air conditioner pumps the heat from your hot house to the outdoors. But wait a minute. Why is your house hot? Because it’s hot outside! So why does the outside want the heat from your house when it’s already hot?

Let’s look at the typical air source heat pump. Looks like an air conditioner. It is, but it’s reversible. If it’s cold indoors, it pumps heat from the outside into the house. But wait a minute. Why is your house cold? Because it’s cold outside. Where is the heat going to come from? Many manufacturers put electric resistance heat strips in their units to make them more effective. And you thought this was going to save you money?

Enter the Ground Source Heat Pump. This expensive piece of machinery does a couple of things. When it’s hot indoors, it pumps the indoor heat into the relatively cooler ground. When it’s cold indoors, it pumps the heat from the relatively warmer ground indoors. The ground is always cooler than hot outdoor summer air, or warmer than cool outdoor winter air. This greatly increases the efficiency of the process, and no more electrical heating strips. A common secondary byproduct is domestic hot water.

Biodiesel and WVO powered Cogen


The Lister CS is a rugged 6hp stationary engine designed in the late 1920s. Its simple fuel injection system is very tolerant to vegetable oil, and as such it can be used to run a 3kW generator set. The waste heat from the coolant and the exhaust can be recovered and used to supplement the domestic hot water and central heating.

Waste vegetable oil is easily obtainable from restaurants for approximately £0.10 per litre ($0.75 per US Gal), and with correct filtration and a Lister CS engine it will provide all the heat and power a typical home requires.
