Reimers designs boilers and water heaters to be the most efficient possible. Double wrapped insulation on the shell and custom cut end wrappers enclose the heating elements. Electric Hot Water Boilers The insulation is resistant to water and built to last as long as the boiler. Very little heat is lost through the K factor rated wrappings. Energy savings is always of interest to customers. With electric boilers the savings is even better when compared to gas and oil fired boilers. Gas and oil fired boilers have to have a stack which loses energy to the outside. Stacks are costly to run through building too. Overall the electric boiler offers many advantages.
