Product Description

At AMC Cliffv's Marine Service, our most popular Espar product is our custom built heater kits. We will work with you to put together the perfect kit that fits your needs, whether that is a brand new heater installation, heater integration with existing systems or replacement of an older heater. Having worked with marine heaters since the mid-90's, we have the experience and the knowledge to make recommendations and help you choose the correct components to put together the perfect heating system for your vessel or vehicle. From hand built wiring to custom-cut ducting and exhaust, we make each heater kit easy to install with included installation guides. We also work with a network of recommended installers if you decide to have someone else install your heater kit. Every heater is tested before it leaves our shop to ensure you are receiving a quality product. While we specialize in building marine heater kits, we have all the components to build custom kits for vans, buses, RV's, etc. Please allow 1-2 weeks to build your custom heater kit.

The Espar Hydronic independent auxiliary coolant heaters offer affordable pre-heating and supplemental heating solutions for many applications, including marine. Their compact size enables a simple installation and eliminates the need for electrical plug-ins. The diesel-fired Hydronic heaters put out a range of BTU's to keep you warm and comfortable, no matter the weather or season. While others wait for the engine to warm up, with on-board heat from Espar, you’re already en route to your destination. Available in a wide range of thermal outputs to closely match your heating needs, Espar heaters are compact, convenient and economical to operate. A Hydronic water or coolant heater offers full internal heat control, supplemental cabin heating, and domestic hot water facilities, while consuming minimal amounts of electrical power and fuel. With your choice of the D5WSC, M-II series, L-II series or a multi-heater system, we can help size the Espar heater to adequately heat your vessel or vehicle. For the marine application, we at AMC Cliffv's Marine employ our exclusive PC Board to make these the most reliable workhorses in their class. Your imagination is the limit when it comes to what features a Hydronic heating system can provide.
