My new buderus, Where are the savings?

Tech Support

"I" try to answer questions to anyone that calls. Simple Logamatic programming can usually be done by anyone. Very seldom do "I" take a homeowner into the "Service" level and make adjustments (there are many contractors who tell the homeowner to call us for programming). "I" use my discrection. "I" am not trying to eliminate or by-pass a contractor- just trying to help. With other issues "I" may try simple things like hit the reset button on the primary control on an oil burner or turn the power on/off on a gas boiler. "I" then suggest calling the technician. Everyone is different so there are going to be different answers. Some local gas utilities provide service some don't, some oil company's do service some don't, some technicians test for CO others don't.

The GB142 dhw priority does not time out (most multizone relay boards do not either). We are looking into the programming to change that. The EM10's are here and ready to go in about 2 weeks (We are working on training and drawings). The CM10's should follow very shortly. Thanks.

We tell them the GB142 will work in a high temperature application but may not achieve the 97% efficiency. The GB142 is a condensing boiler and is designed for that. The higher the return water temperature the lower the efficiency.

Do multizone relay's offer any assistance if the priority zone fails?

So ......... what is a homeowner to do

if the installing contractor will not make right any problems on the job ? What is a homeowner to do if they need some general questions answered over the phone ? What do they do , hire another contractor right off the bat and hope and pray they fare better with the new guys and fix what's wrong ? Or maybe , just maybe , call the boiler co first and see if they can help ? Sure you and me and many others got some inaccurate answers from tech support people . Does it happen often ? Often enough to shut out homeowners from calling the company direct ? I would seriously think twice about buying from a manufacturer that had a tech support line and did NOT accept inquiries from the homeowners . From homeowners who BOUGHT THEIR EQUIPMENT ! Not that I have much of a choice - but Burnham , Peerless and Weil Mclain ( our main brands ) are all very happy to field customer calls . Saying that's " throwing the contractor under the bus " is debatable , depending on what the frig is wrong with they system . And of course , I know there is a limit to how much info they should give out to a customer . How could you ask a homeowner to check gas pressure , clock a meter , check for proper draft , CO , CO2 - when many installers don't know how to do it or have the equipment ?

Joe is right a switching relay doesnt have any automation when dhw priority stays on. relying on the constant circulation theory to avoid freezing for ahu's in cold spots in not a very good choice. try a flat plate hx or glycol in the whole system.

Taco does

My circulator relay from Taco will turn heat circs back on if the DHW call is longer than an hour(not positive about time). It does that because I put in the little card that is an option. Before I had priority control the moving water prevented a flood when the burner went off on safety while I was away.

The way I do it

get my degree-day info here for the billing period in question:

http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/cdus/degree_days/

You can view and download degree-day info by the week or month on this site. Then I calc the number of gallons (for oil) or therms (for natural gas) used during that period. The result is gallons or therms per degree-day. If there are other loads such as domestic water, dryer or stove on the same gas or oil account, this can muddle the results a bit- but not much, since these loads tend to be fairly constant.
