high mass vs low mass boilers plumbing perspective

Some of the extended fuel savings we observe and the delta-t manufacturer claims seem to be due largely to this radiation profiling effect. Another contributor is the lowered system operating temperature effect of using a very high mass cast-iron boiler vs. contemporary low-mass units.

2019-12-1 · I don't know much about Lochinvar's low mass combi boilers. Combi boilers tend to be poor fit for most low-load houses, but with high mass slab radiation operated as a single zone that won't matter as much. Navien's have a track record, and with reasonable local support it would do fine, without local support walk away and look for something else.

TDS stands for total dissolved solids, and represents the total concentration of dissolved substances in water. The pH value of a water source is a measure of its acidity or alkalinity. The pH level is a measurement of the activity of the hydrogen atom, because the hydrogen activity is a go

PEACHTREE CITY, Ga. (Aug. 1, 2013) – Based on the Department of Energy's updated efficiency-test procedures, the Rinnai E Series Combi Boilers recently earned a 95.5 percent AFUE rating, making them the most efficient combi boilers currently on the residential market.

Solar thermal flat plate or evacuated tube collectors? This is an incredibly common question in the solar thermal industry. Strangely enough, many people weigh in, and take different sides. Like a Red Sox vs Yankees type of rivalry, it's a heated debate. In the end, it depends on the job you're work

High Mass vs. Low Mass boilers - Plumbing Perspective. Choosing between High Mass or Low Mass boilers. By Jack Daniels. There has been much discussion on low and high mass boilers as of late.

Thermal Mass Trade-Offs: Heating vs Cooling, Insulated vs Un-insulated Floor Slabs, How to use thermal mass with radiant heating systems. How to use thermal mass with radiant heating systems When or in what climates should we insulate below the slab of a radiant heat floor design? When or in what climates is it better not to insulate below the floor slab in a radiant heat design?

2019-10-2 · This practice becomes unnecessary with sufficient thermal mass. High thermal mass designs I have seen require a dedicated footing in the ground. This is a significant additional expense and inconvenience vs. a conventional woodstove, which can rest on a conventional framed wooden floor.

2019-11-30 · Employing high-performance HVAC equipment in conjunction with whole building design can result in significant energy savings. Typically, a 30% reduction in annual energy costs can be achieved with a simple payback period of about three to five years. And, if the payback threshold is extended to seven years, the savings can be about 40%.
