The Court is unpersuaded that N.J.A.C. 5:10-14.3(d) imposes any regulatory duty on landlords to cover in-unit radiators with insulating material or a cover. The regulatory scheme provides no evidence of an express or implied intent to include radiators as part of the “heating system” required to be insulated. Having concluded that no such regulatory duty has been imposed, and because the tenants in this case maintained exclusive control over the heat emanating from the radiator, the Court declines to impose on landlords a new common law duty to cover all in-unit radiators.
