DEVI mats are very convenient for electrical heating system installation on large areas. Benefits of Under tile heating. • Warms the floor under your feet in even the coldest weather. • Provides a gentle background heat for your comfort. • Eliminates mould caused by exposure to dampness in wet zones. • Quickly dries floors and in so doing, greatly reduces the risk of slipping and injury. • Once installed no maintenance is required. - [In Slab Heating] (https://www.devi.co.nz/In-Slab-Heating): In-slab heating is a heating cable fixed to the top layer of the slab reinforcement before slab pour. Cables are installed with the top mesh in approximately 30-40mm of concrete. The system runs during off-peak hours to cut energy costs and maximise system efficiency. Our heating cables heat the slab, in turn warming the floor covering above. During peak hours, the system runs on the stored energy accumulated during off-peak hours. The thermal mass the slab provides retains heat for long periods of time, insulating the slab from the outside elements minimises heat loss. This system is usually used in new construction before the slab is poured. Benefits of Electric in-slab floor heating. A correctly designed floor heating system ensures heating performance in all weather conditions. In coastal environments, none of the heating system is located outdoors where products are exposed to salt laden air. Once installed no maintenance is required. When used in conjunction with low tariff/night rate power, electrical in-slab heating is efficient and spreads the peak energy demand. Kills mites and bacteria in floor coverings which make for a healthier ‘breathe easy’ home and a less allergenic environment. Prevents unhealthy mould forming beneath floor coverings. Electric in-slab heating can easily be integrated with solar systems to heat your home with free power. Simpler and much cheaper to install than a comparative hydronic system. Electric in-slab heating cables are uniquely suitable to heat your home during the day with power collected at night. No visible radiators, maximising space utilisation and interior design flexibility. - [Trace Heating, Self Limiting Cables for Frost Protection] (https://www.devi.co.nz/category/260746): Frost protection systems are installed where there is a need to prevent water and sanitary pipes from freezing and becoming ice damaged. Temperature maintenance systems ensure that hot water or fluid pipes maintain the required temperature. The pipe tracing systems consist of electric heating cables, electronic thermostats, and installation accessories. Pipe tracing systems can be used on the inside and outside of pipes, indoor and outdoor pipe networks and pipes above and below ground. Pipe tracing systems should be installed in the early stages of construction. It ensures safety and prevents any hazard of damages caused by ice. - [Historical / Obsolete Products] (https://www.devi.co.nz/devireg-historical-products): Nothing lasts for ever. Some of our products have served us well for many years but their time has come. When a product becomes obsolete there is normally a direct replacement being newer, better, and more advanced. - [Vineyards] (https://www.devi.co.nz/blog/Vineyards): Electric heating protects grapes against frost damage and offers a sustainable solution for clean future through low energy consumption during the frost period, saving up to 87% of the harvest. - [Cold Stores] (https://www.devi.co.nz/blog/Cold-Stores): In areas where very cold dry air meets warm moist air, the moisture contained in the warm air flow may settle on the cold surface and turn into ice. Cold store solutions prevent frost heave and ensure frost protection in industrial buildings, supermarkets with cold rooms, cold stores and ice stadiums. - [Underfloor Heating] (https://www.devi.co.nz/blog/Underfloor-Heating): Electric heating for indoor ensures comfortable room temperatures, be it at home, at the office, in a workshop, sports hall or virtually anywhere where comfortable heat is required. Equally important is the fact that our floor heating system can be installed in all floor types whether they are new concrete or wooden floors or renovated floors. - [Pipe-Tracing Solutions] (https://www.devi.co.nz/blog/Pipe-Tracing-Solutions): Liquid supply systems, such as fresh water pipes, waste water pipes, cooling water pipes, supply water pipes and sprinkler systems can be prevented from freezing during winter times, with electric heating frost protection systems. - [Asphalt Ice and Snow Melting System] (https://www.devi.co.nz/blog/Asphalt-Ice-and-Snow-Melting-System): Installation of the Ice & Snow Melting System ensures a steady solution to address cold weather-related problems. Main purpose of the system is to melt and remove snow and ice from ground surfaces. - [Domestic Hot Water] (https://www.devi.co.nz/blog/Domestic-Hot-Water): The electric heating system for domestic hot water maintains water supply at the required temperature level, provides appropriate disinfection to suppress the Legionella bacteria, reduces water waste as you get hot water immediately and savings when a circulating pipe system is unnecessary. - [Sport Fields] (https://www.devi.co.nz/blog/Sport-Fields): Electric heating in the sport fields or stadiums serves as a growth and restoration stimulator for natural grass. It ensures a better pitch that can extend the playable season, irrespective of the season or location and serves as an energy efficient solution preventing the field from being adversely affected by frost and snow during the winter. - [Ground Ice and Snow Melting System] (https://www.devi.co.nz/blog/Ground-Ice-and-Snow-Melting-System): Large outdoor spaces, such as car parking areas, driveways, pavements, outdoor steps, loading platforms, ramps, bridges and drainage areas can be cost-efficiently protected during winter times, by ice and snow melting applications. - [Roof Protection System] (https://www.devi.co.nz/blog/Roof-Protection-System): The ice and snow melting system for roofs and roof gutters can be applied for virtually any type of roof constructions to prevent meltwater accumulation in roof gutters and to reduce damage to constructions like frozen facades and roofs. The typical applications are roof constructions, roof gutters, downpipes, flat roofs and valley gutters.
