The Monster in the Basement- converting old boilers to modern HE models.

Coal Fed Monster

I have a story to tell, a scary story. A story of a monster living in a basement, a monster with a ravenous appetite. But don’t worry, there is a happy ending.

The monster wasn’t always a monster. When it first moved into the old Victorian home in 1905 it was loved as a modern marvel. It provided warmth for its family throughout the coldest winters and all it needed was to be fed with a shovel full of coal a few times a day.

But as time moved on the monster consumed more and more coal and spit out a dirty, belching breath that polluted and scarred and nobody liked it anymore, except Arthur Scargill, who was a bit odd.

Arthur Scargill

So the monster changed. It started eating Natural Gas. Around 1970, a lot of things that liked coal became full of gas (again, Arthur Scargill comes to mind). And the family were happy again. For a bit.

For gas became expensive and the monster just could not get enough of it. The family were cold in the winter and this made them cross. They started to complain about the monster and wondered if anything could be done about it.

And the answer was, “yes”. Continue reading

RETRO-FIT UNDER FLOOR HEATING, AKA “Staple-Up”.

 

retro fit under floor heating

Under floor heating "staple-up"

Yes, even with existing hard-wood, you can have radiant floor heating!  There are a great deal of misconceptions around radiant floor heating and, in particular “staple-up”.   The comfort of under-floor heating can be retro-fitted to existing floors, the process is often referred to as Staple-up as the tubing or, more often, the insulation is attached with staples.   It is a very effective way to get the comfort and efficiency of a radiant heating system into an older home.

I once had a customer complain that he had a problem with his staple-up system, “When my in-laws visit, they take off there shoes and socks to enjoy the warm floor, I hate looking at their feet!!”.

High Efficiency Water Heater- The alternative to Tankless.

We are all aware by now that the standard storage tank water heater is out-dated technology that does not meet our needs for fuel efficiency and reduced carbon emissions.  We know that 45% of the gas used in our homes is attributed to our Domestic Hot Water needs.   Many people have researched tankless water heaters, also known as Flash water heaters or on-demand water heaters and found that they can increase efficiency dramatically and produce endless hot water with reduced carbon emissions.  This same research may have led them to the conclusion that there are some draw backs to tankless technology- long delays in hot water delivery to fixture with increased water wastage and high cost of installation in some cases.

There is another solution to the Water Heater problem, High Efficiency Condensing Water Heaters.

Solar Hot Water Installation with Wi-Fi

Bay Area Hot Water From The Sun

Capturing the suns energy for pre-heating a homes hot water has been with us since man started bathing.  In recent years the solar hot water industry has had a new lease of life with increasing energy costs and concern for climate change. The government has given home owners added incentives with tax credits.

The very latest advancement in solar hot water technology is the introduction of web based performance monitoring.  The Helio-Pak Pro from Heliodyne, a local solar manufacturer based in Richmond CA., has a built in wi-fi transmitter that the installer or home owner can access from there PC. , lap-top or smart phone.  This allows for performance monitoring  and trouble shooting from, well, anywhere.

Comfort you can feel. Comments from homeowners with radiant heating.

Solar Thermal- hydronics mechanical room

Solar Thermal- hydronics mechanical room

A selection of clients give their comments on their radiant heating systems.

Dan and Liz, Piedmont California.

Boiler: Baxi Luna HT1.330

Heat:  Radiant slab on the ground floor with radiators on the second floor.

Zones: Four zones Taco ZVC zone control and ESP zone valves, Taco zone circulator.

Hot water:  In-direct storage tank with Helio-dyne solar heat exchanger (2 4×6 black paint solar collectors) with hydronic back-up.

Comments:  “It doesn’t feel like a heating system, the house just stays nice, its perfect.  We came back from a vacation, the house was cold, but by the time we finished our burritos, the whole house was toasty warm”- Liz

“We have 1800 square feet and we pay $200 per month in gas. Our neighbor has a smaller house and pays $300 per month”- Dan

“We love it” Liz

“Its very good”- Dan. Continue reading

Radiators- Affordable Radiant Heat.

I really like radiators as a way to heat a home. There is no question that a radiant floor system is the best and most comfortable way to heat a home, however there are many times where it is not practical or cost effective to install. We frequently have retro-fit projects where we are putting staple-up below a floor from a crawl space but to put it on the second floor would involve major demolition and repair cost to expose a second floor space. Sometimes, an addition might be a good candidate for a heated slab but the budget does not extend to a retro fit staple-up installation.

Green Plumbing- A Case Study

On Friday, May 14th 2010, a City of Berkeley building inspector signed off on the final inspection on one of the most forward thinking buildings in the Bay Area.

I was very fortunate to be involved in the design and installation of the plumbing and mechanical systems in this new construction Berkeley home that incorporates almost all of the green plumbing technologies available at this time.

The home-owner on this project is deeply concerned about environmental change, when it came time to build her dream home, she was determined that it should have a minimal impact on the planet. Our homes generate a great deal of the carbon emissions that contribute to global warming and diminishing resources including fossil fuels and water are concerns for everyone.

Smart Heating

Hydronic Heating Boiler Room

Smart and Simple Mechanical Room

Hold your hand over a candle, blow out the flame and the heat is immediately lost.  Now, boil a pot of water.  When you turn off the heat, the water is still hot.  In fact, the heat energy in the pot of water can be picked up and transported to another room, it can be stored and used later and its heat is kind and comfortable.
