Choosing a Wren Kennel Heater
, by Martin Forshaw, 3 min reading time
Keeping dogs warm and comfortable in a kennel, cattery or whelping area is about more than choosing a heater based on breed alone.
The correct heating setup depends on the size and construction of the space, insulation, outside temperature, ventilation, where the heater is installed and whether you are heating an adult dog, a bitch with puppies or a young litter.
A well-insulated, draught-free sleeping area will need far less heat than a large, exposed or poorly insulated kennel.
Start with the environment
Before choosing a Wren heater element, consider:
-
The size of the sleeping area
-
How well the kennel is insulated
-
Whether there are floor or door draughts
-
The usual outside temperature
-
Whether the kennel is indoors, outdoors or in an unheated building
-
The dog’s age, size, coat type and health
-
Whether the heater is for an adult dog, a whelping bitch or newborn puppies
-
The height and position of the heater
-
Whether the dog can move away from the warmed area
A heater should provide a comfortable warm zone, not heat the entire enclosure excessively.
Adult dogs
For healthy adult dogs, the main aim is usually to provide a dry, draught-free sleeping area with gentle background warmth where needed.
Small, short-coated, elderly, very young or unwell dogs may need more support than large, heavily coated or hardy breeds.
Always monitor the dog’s behaviour. Signs that a dog may be too cold include persistent shivering, curling up tightly, reluctance to settle or seeking constant contact with the heat source.
Signs that a dog may be too warm include panting, moving away from the heater, restlessness or seeking cooler areas.
Whelping bitches and newborn puppies
Newborn puppies cannot regulate their body temperature effectively, so they need a warmer local area than adult dogs.
However, it is important that the bitch and puppies can move between warmer and cooler areas. The mother may become uncomfortable if the entire whelping area is heated to the same level needed by the litter.
Position the heat source so that:
-
It is securely installed and out of reach
-
It cannot be knocked or pulled down
-
It is clear of bedding, straw, towels and other combustible materials
-
Puppies and the bitch can move away from the direct heat
-
The temperature is monitored regularly
-
The area remains well ventilated without cold draughts
For young puppies, use a suitable thermometer and follow guidance from your vet or breeder, particularly for premature, orphaned or unwell litters.
Choosing the right Wren heater element
Wren heater elements are available in different wattages to suit different kennel sizes and conditions.
As a general guide:
-
Lower-wattage elements may suit small, well-insulated sleeping areas or situations where only gentle background warmth is required.
-
Higher-wattage elements may be more suitable for larger spaces, exposed kennels, colder conditions or taller installations.
-
Heater regulators can be useful where conditions change through the day or across the seasons, allowing the output to be adjusted rather than running at full power continuously.
The best choice is based on the whole environment, not breed alone.
Safe installation matters
Always follow the manufacturer’s installation and operating instructions.
The heater must be securely fitted, positioned at an appropriate height and kept well clear of bedding and other flammable materials. Electrical work should be carried out by a competent person where required.
Never rely on a heater as the only protection against poor insulation, damp conditions or serious draughts.
