Taylorjm, every tankless I've ever seen has a combustion blower and every gas/propane furnace does as well. You will never get the efficiency without it. I think the delay to fire is about 1/2 second and you will never notice it. I can run my kitchen faucet at any temperature from warm to scalding hot and the unit fires every time. Why keep 40 to 60 gallons of water hot all day long when it is not needed. I also moved mine from a hall closet to under my crawl space where it is out of site.
I still tell my wife every time she is washing dishes to try and keep from turning the hot water on and off every time she rinses a dish. I'm not sure if it hurts anything but it cycles on and off every time she rinses.
